18.1 About Screen Design Aid
Screen Design Aid (SDA) is an interactive feature you use to design and maintain screens. This full-screen editor validates your work against the Data Dictionary and adds records to vocabulary overrides. You can work with multiple record formats simultaneously and you can move fields from one format to another.
Below is a list of some features of SDA:
-
Design is conducted in a safe work environment. If you make a mistake you can exit without changing a screen's Data Description Specifications (DDS).
-
Screen specifications are stored in data structures in the QRECOVERY library. This is similar to the IBM recovery of SEU.
-
You can create a screen in normal mode (80 columns by 24 rows) or wide mode (132 columns by 27 rows). You can also design wide screens on 80 column devices using a windowing facility.
-
Answering initial yes/no options allows you to create a basic screen skeleton for a subfile, non-subfile or window-style screen.
-
SDA is fully integrated with the Data Dictionary and vocabulary override files. You can place fields on the screen by referring to a Data Dictionary name and override default attributes, if necessary. You can place vocabulary override fields on the screen and, if desired, modify their contents through the full screen.
-
SDA is fully integrated with the system database. You can select fields from the system database, create a pick list and then reorder fields in the pick list. You can place fields on the screen individually or all at once by pinpointing locations on the full screen with an ampersand (&) or asterisk (*).
-
SDA has full screen capability. You can add, change, move, or delete fields by entering control characters directly on the screen.
-
Unlike the IBM SDA, JD Edwards World SDA allows you to work with multiple record formats at one time. You can display and change any combination of formats simultaneously (as long as they do not overlap). You can also move fields from one format to another.
-
SDA allows you to simulate a screen at program execution time. You can run the simulation for any set of conditioning indicators to represent a particular error condition or other program functions.
18.2 Editing Commands
Standard editing commands available in SDA include:
| Command | Description |
|---|---|
| *DEL | Delete fields (used in Field Definition window) |
| d (cannot be uppercase D) | Delete fields (used in Field Definition window) |
| <<, >> | Shift fields to the left or right |
| (xx...xx) 'xx...xx' | Literals (use apostrophes) |
| - | Move from position. |
| = | Move to position. |
| - - | Move block from position |
| = | Move block to position. |
| F7 | Restore the screen if you accidentally press Field Exit or a power failure knocks you off. |
Precautions and automatic features of the SDA include:
-
Do not use the INSERT or DELETE keys while in the actual design portion of SDA.
-
SDA automatically assigns editing indicators.
-
Indicators 40 to 79 are reserved for editing.
-
Indicator 40 is reserved for the Action Code field.
-
Indicator 41 is reserved for the key fields.
-
If you use all available indicators, you will get an error message.
-
-
Indicator 37 is used in subfile screens to highlight all fields on the last line of the subfile to indicate that no more records exist.
18.3 Prefix Standards
Prefix standards for use in the SDA include:
18.4 Field Name Standards
Field name standards for use in SDA include:
18.5 Updating or Adding Fields through SDA
18.6 Working with Screen Design Aid
To work with Screen Design Aid you must have access to the source file.
18.7 Function Key Exits
F12 - Return to Previous Panel
F12 - Exits you out of the current screen or utility and returns to the screen you were on previously.
Use F12 instead of F3; however, if you are calling another program outside of SDA (for example: F13, F24), you must use F3 to return to SDA.
18.8 Updating an Existing Field
Place an asterisk (*) in front of the field (in the attribute character). This will bring up the Field Definition window.
Figure 18-2 Field Definition portion of the Item Search screen
Description of "Figure 18-2 Field Definition portion of the Item Search screen"
| Field | Explanation |
|---|---|
| Dict Name | Identifies the four-byte data item name from the Data Dictionary.
This is the only required field for most data items, the rest will default. |
| Text | Describes the Dictionary Name.
VTX fields contain the soft coded description from the Data Dictionary that updates F9220 (Vocabulary Overrides). |
| Data Type | S – Numeric data items.
A – Alphanumeric. Blank – (w/decimal position blank in Size field)defaults to A. Blank– (w/decimal position defined in Size field) defaults to an S. All – JD Edwards World fields are defined as A. |
| Field Name | Identifies a screen field name.
|
| Row/Column | Two 3-digit fields that define the row and column location of field. |
| Field Use | How the data is to be used on the screen.
I – Input only O – Output only B – Both input and output H – Hidden field M – IBM Message field |
| Size | Two fields identify the length of the data item and for numeric fields, the decimal places.
|
| Text Form | For VTX fields, identifies the field from the Data Dictionary that is used for headings.
R – Row Description. C – Column Heading 1. D – Column Heading 2. |
| Dft Cursor | Starting cursor position on a data entry screen, Y or N. |
| Edited | Should the field be checked for error conditions, Y or N.
|
| Lower Case | To allow lowercase, Y or N. |
| Change | CHANGE keyword is in effect, Y or N. The indicator will be set on whenever the value in this field is changed. |
| OVERDTA | OVRDTA keyword is in effect, Y or N. Used with PUTOVR to override data that is in a field already on the screen. |
Note:
You should edit all input capable fields. (There will be a "Y" or "K" in the "Edited" field).| Field | Explanation |
|---|---|
| Duplicate | Duplicate the data. Only valid for a SFL format. Puts the DUP keyword in the screen/report DDS but the Program Generator does not generate any code to enable this. |
| OVRATR | OVRATR keyword is in effect, Y or N. Used with PUTOVR to override display attributes of a field on the screen. |
| Field Cond | Field Conditioning Indicators. Determines if the user can see the field or not. |
| Condition Indicators | To set a condition indicator on a field, enter a Y in the first blank to the right of the desired condition. You have the option of entering up to 3 indicators to be associated with the condition. Three spaces are provided to allow an N prior to the two digit indicator to create a negative condition. The allowed conditions are:
RI – Reverse Image HI – Highlight UL – Underline ND – Nondisplay BL – Blink PR – Protect PC – Place Cursor A blank or N will deactivate the condition. |
| Color | F8 toggles to display the color attributes for the field. The first blank to the right of each color controls the order that multiple colors will appear in the DDS (1-7). If multiple colors are defined, the first enabled color displays and the remaining colors are ignored. A blank or N disables the color. The color values default based on whether you selected JD Edwards World or SAA colors in QJDF. |
18.9 Accessing Fast Path Create for a New Screen
When you design the format for a new screen, you have the option to use Fast Path Create.
To access Fast Path Create for a new screen
-
Locate your screen and enter selection 10.
If SDA cannot find the existing DDS for your screen, the Create New Screen displays:
-
Press Enter and SDA begins the creation of your screen based on what you specified.

Description of "Figure 18-10 Blank Item Master Information screen"
18.12 Using the *BOTH and *ALL Features
The Field Definition window allows you to enter some special keywords in the Field Name field. Two of these special keywords are *BOTH and *ALL.
This feature provides for placement of multiple fields with a single entry.
18.12.1 Using *BOTH
If you use the keyword *BOTH with a valid data dictionary item, screen design will place a VTX field and a screen (VD) field on the screen.
On Field Definition
Figure 18-11 Item Master Information screen
Description of "Figure 18-11 Item Master Information screen"
Type "*BOTH" in the Field Name
When you enter *BOTH, the following screen displays in the SDA design area for the Unit of Measure field:
Figure 18-12 Item Master Information screen
Description of "Figure 18-12 Item Master Information screen"
18.12.2 Using *ALL
If you use the keyword *ALL with a valid Data Dictionary item, screen design places a VTX field, a screen (VD) field, and a VC0 field on the screen.
On the Field Definition window
Figure 18-13 Field Definition portion of the Item Master Information screen
Description of "Figure 18-13 Field Definition portion of the Item Master Information screen"

You can enter a B in the Field Use field to override the default and change it to both input and output.
If you enter B in the Field Use field, the Edited field defaults to Y. The Condition Indicators default to Y and the next available editing indicator is assigned to that field. |
| VTX - Screen Text field |
|
| VC0 - Screen Constant field |
|
18.12.3 Understanding the SDA Exit/Save Function Key
F3 - Saves, exits, or does both from Screen Design Aid.
| Field | Explanation |
|---|---|
| Save DDS (Y/N) | Saves the DDS and updates or creates Vocabulary Overrides and Function Key definitions. |
| Member ID | The record of the Software Versions Repository member to be copied.
Screen-specific information Name of the screen. |
| File ID | Identifies the file that will contain the source code. |
| Src Library | Identifies the library where the source code resides. |
| Description | The description of a record in the Software Versions Repository file. The member description is consistent with the base member description. |
| Function Code | Should be DSPF for a Screen. |
| Return to Edit (Y/N) | EOJ or allows return to SDA. |
18.13 Compiling Your Screen
From the Software Versions Repository screen
Figure 18-16 Software Versions Repository screen
Description of "Figure 18-16 Software Versions Repository screen"
18.14 Screen Design Standards and Tips
18.14.1 Title
A screen title is limited to 30 characters and should match the Software Versions Repository (F9801). The title you enter in SDA updates the vocabulary overrides record for the screen. If you access the screen using a menu selection, the menu selection name overrides the screen title. If you access the screen using a selection option or function key, the vocabulary overrides title is used.
18.14.2 Line 24
You should document function keys on the right side of line 24 and you should document options on the left side. The following guidelines should also be followed:
-
List both the options and function keys in numeric order.
-
F24 should always appear and should say MORE KEYS or MORE.
-
F4 should always read MORE DETAIL or DETAIL.
-
Do not include standard exits of F3, F7, F22, Help, Rollup, Rolldown.
-
Line 24 should be in reverse image during an error condition. Line 24 is conditioned to appear in reverse image on screens based on indicator 93.
-
If you specify *SAME for the field "Error Text" for Line 24 in vocabulary overrides, then the text displayed is the same as the text specified for the normal Line 24.
18.14.3 Windows
Within a window, line 24 should include F3 and F24 when the window is initially displayed. When designing windows in SDA, fill in unused line space with literal fields to prevent data on the calling screen from showing through on the window. You can add the literal fields on the SDA screen as blanks with a single quote on each end or through the Field Definition window.
18.14.4 Default Cursor
You set the default cursor attribute to Action Code for the input field closest to the upper-left corner of the screen.
18.14.5 Fold Area
Keep the number of Fold Area lines to no more than two lines to avoid excessive use of the cursor keys when the Fold Area is open.
18.14.6 Description Fields
Define all description input fields to allow for uppercase and lowercase letters DDS keyword CHECK(LC). Use VC0 descriptions when a field's value has no obvious meaning and you can retrieve a description from a master file or user defined codes.
18.14.7 Alpha Fields
Because of the dynamic nature of international currency, you must define every field as alpha. The only exception is that you can define hidden fields as numeric. JD Edwards World scrubbing routines handle the two-way conversion between numeric data in the file and formatted alpha screen fields.
18.14.8 General Aesthetics
The following are things you might want to consider when designing screens. They are guidelines that will give your screens a more professional look.
Line up fields vertically. This includes row descriptions, input fields, and description fields. Fields on the left side of the screen should be in column space 2 (column 1 is needed for the attribute byte).
When entering a descriptive heading to group related fields, use up to 40 characters for the description (or as long as space permits). Highlight the heading and end it with a colon. Underneath the heading, indent the group of fields one space to the right.
Figure 18-19 An Example of Grouped Fields
Description of "Figure 18-19 An Example of Grouped Fields"
Use the following as your standards when spacing different screen elements:
Figure 18-20 Standards for Spacing Screen Elements
Description of "Figure 18-20 Standards for Spacing Screen Elements"
-
Separate column headings with one space.
Figure 18-21 An Example of Separating Columns
Description of "Figure 18-21 An Example of Separating Columns"
-
End row descriptions with at least one period followed by a single space before you begin associated input fields.
-
Indent Fold Area fields one or more spaces to offset them from regular subfile.
-
Use two or more spaces to separate Fold Area data fields from row descriptions that follow on the same line. End Fold Area row descriptions with a colon instead of periods to aid legibility.
Figure 18-24 Ending Fold Area Row Descriptions
Description of "Figure 18-24 Ending Fold Area Row Descriptions"
-
Insert a blank line between header and subfile information.
Figure 18-25 Separating the Header and Subfile Rows
Description of "Figure 18-25 Separating the Header and Subfile Rows"
-
When possible, insert a blank line between the title and first field. Begin fields on line 3 unless you need to use the upper right corner of line 1 and 2.
18.15 Adding Screen Fields Using Pick List
From the SDA screen:
-
Access the Records Formats List using the F10 key.
-
Press F10 to display the Record Formats List.
Use this screen to select database fields and maintain record formats, record types, fast path files, and record format keywords.
18.15.1 About Record Formats
Several Record Format Types are valid for screens. Currently, they include:
-
Present in all subfile screens. Contains all of the fields in the header or top portion of the screen, including the subfile column headings.
-
SFL - Subfile
Contains all the fields in the subfile portion of the screen, including the fold area (if applicable).
-
RECORD
Present in all screens. In subfile screens, contains VDL24 (line 24 text). In non-subfile screens, can contain all fields on the screen, including VDL24.
-
SFLMSG - Subfile Message
Displays error message text. JD Edwards World does not use this format because errors are handled through RPG programs.
18.16 Selecting Database Fields
There are two methods of selecting database fields for placement on the screen:
-
With Fast Path
-
With the File Selection List
| Method | Description |
|---|---|
| Fast Path | Type 1 next to the format on which you want to place the fields and enter a file name under the Fast Path File column. |
| File Selection List | Type 1 next to the format on which you want to place the fields but do not enter a file name.
Accesses a file selection screen where you can specify multiple files and libraries from which to select database fields. |
To select a database field using Fast Path
-
On the Record Formats List screen, enter a Fast Path File for the specified format.
-
Press F21 to select all the fields for the file instead of selecting them individually.
Based on the record format for which you are using the Field Selection List, the following information is the default:
-
For a subfile control record format, the HDG field will default to R for the type of heading and the Use field will default to B for input/output.
-
For a subfile record format, the HDG field will default to D for the type of heading and the Use field will default to B for input/output.
-
For a non-subfile screen, the HDG field will default to R for the type of heading and the Use field will default to B for input/output.
-
For a report, the HDG field will default to D for the type of heading and the Use field will default to O for output.
-
To select database fields using the File Selection List
From the Record Formats List screen:
-
Enter the files from which you want to select fields.
Fields for files requested will be displayed through the Field Selection List screen.
-
Select fields using the same techniques as in the Fast Path method.
Note:
If you select a key field, that field is edited as the key of the screen. An edit indicator of 41 is assigned.18.17 Placing Fields on a Screen Using a Pick List
To place fields on a screen using a Pick List
On the Item Master Information screen
Figure 18-34 Item Master Information screen
Description of "Figure 18-34 Item Master Information screen"
-
Type either one or more ampersands (&) on the SDA screen where you want to place the fields from the pick list you created.
If you place more than one &, make sure that you allow room for all of the fields that are returned to the screen, so that you do not overlap fields.
-
On the Field Selection screen, verify the information that is on the screen (VTX field - HDG, 30-character description - D, and field Use - USE), as well as the order that they will be brought back (the sequence number), and row description length.
-
To add a Fold Area to a subfile, place an asterisk (*) or ampersand (&) on the second line in the subfile format of your screen. If you need a second line in the Fold Area, you can place an asterisk (*) or ampersand (&) on the third line of the subfile format. HDG should be "R" when adding fields to the fold.
