Defining Traceability Sets

To define traceability sets, use the Traceability sets component (QS_TRACE_SET). This topic provides an overview of traceability sets and discusses how to create traceability sets.

Create a traceability set.

A traceability set is a group of fields that specify the tagging or trace information that is collected during inspection. Each set comprises the trace fields that are defined within its parent quality function. Use traceability sets to:

  • Assign to one or more control plans.

  • Collect traceability item information at the time of inspection.

  • Maintain process or product content and handling information, such as lot or serial ID.

    This information is useful in determining causes of variation or in performance comparisons.

Use the Define Traceability Set page (QS_TRACE_SET) to create a traceability set.

Navigation:

Quality > Establish Control Plans > Traceability Sets > Define Traceability Set

Traceability fields are inherited from the parent quality function. You cannot add additional fields, but you can edit or inactivate field entries.

You can establish each field at the individual or subgroup level. If the field is set as Individual, the system prompts you for trace data for each sample in a subgroup. For example, if a subgroup size is five, and a traceability set has a Lot ID field set to Individual, then you are prompted for five lot numbers—one for each measured value in the subgroup. In the same example, if the field is set to Subgroup, then you are prompted for one lot number for the entire subgroup.

Field or Control

Description

Active

Select to activate the trace field. The system prompts for and displays only active fields during data entry. You can activate up to 12 fields for a traceability set.

Field Name

The actual trace field (PeopleSoft object) name.

Level

Select the level at which you collect and store the trace field information:

Individual: A trace field value is entered for each individual sample of a subgroup.

Subgroup: A single trace value is entered for the entire subgroup regardless of subgroup size.

Input Type

Specify how data is entered in the trace field:

Auto Dflt (auto default): The default value is read from the input source or internal call-out routine and appears on the data-entry page. Override this entry by typing into the field or selecting from a prompt table list.

Fixed: A value is read from the input source or internal call-out routine and appears on the data-entry page. You can't override this entry.

User Input: Enter values directly into the field or select from a prompt table list.

Prompt Table or View

Specify the prompt table to associate with the trace field. This is the table or view that the system uses to populate drop-down lists during data entry. The default is inherited from the quality function, but you can override it here. Prompt tables are assumed to be Structured Query Language (SQL) tables or views that are created in a working database and are validated by using the Tools Record Definition table (QS_PSRECDEFN_VW). This field is not applicable for an input type of fixed.

Custom Field Format

Enter the name of an optional PeopleTools custom field-formatting object to use for display or input control.

Input Source

Set the source for populating default or fixed-trace values. The trace field value is read from this source at the time of data entry if either Auto Dflt or Fixed is specified for the Input Type field. This field is not applicable for an input type of user input. Options include:

%Datetime (datetime): Gets the current server date and time.

%OperatorId (operator ID): Gets the current user ID.

&G_TRACE_01 through &G_TRACE_12: Gets the value of a global PeopleCode variable that is defined prior to starting data entry.
