• vary the job quantity and/or start and completion dates to determine scheduling and requirement constraints

• view both on-hand and available to promise quantities for simulated component requirements

• vary the bills of material and/or routings and their associated revisions and revision dates

   To simulate a discrete job:

1. Navigate to the Simulate Discrete Jobs window.

2. Select the simulation Assembly.

You can only simulate standard discrete jobs with assemblies, although routings are not required.

If you set the WIP:See Engineering Items profile option to Yes, you can also simulate jobs for engineering items.

You cannot select an assembly that has a primary routing that is flow related. If you do, a warning is displayed and you are prompted to enter another routing designator. See: Creating a Flow Routing.

3. Enter the job Quantity.

4. Enter either a job Start Date and time or a Completion Date and time.

You can enter start dates and times earlier than the current date to maintain relative date priorities for department schedules and material requirements

5. Optionally, select an Alternate bill of material. See: Primary and Alternate Bills of Material.

You can select an alternate bill if alternates have been defined for the assembly you are building. This bill of material is used instead of the assembly's standard bill of material.

6. Select the bill Revision and Revision Date and time.

The bill revision and date determines which version of the bill of material is used to create job component requirements. The start date of a standard discrete job can be used to default the bill revision and revision date. If a start date is not selected, the revision and revision date are derived based on fixed and variable lead times of the assembly. See: Item and Routing Revisions.

You can explode item revisions that have ECOs with Release, Schedule, and Implement statuses against them. If you set the WIP:Exclude Open ECOs profile option to No, you can also explode revisions for ECOs that have an Open status. See: ECO Implementation By Status.

7. Optionally, select an Alternate routing. See:Overview of Routings.

You can select an alternate routing if alternates have been defined for the assembly you are building. This routing is used instead of the assembly's standard routing. If the WIP:See Engineering Items profile option is set to Yes, you can select engineering routings as alternates. See: Work in Process Profile OptionsProfile Options and Primary and Alternate Routings.

8. If the assembly has a routing, select the routing Revision and Revision Date and time. See: Item and Routing Revisions.

The start date of a standard discrete job can be used to derive the routing revision and revision date. If a start date is not selected, the revision and revision date are derived based on fixed and variable lead times of the assembly.

   To save a simulated job:

1. Choose Save Simulated Job from the Special Menu. The Save Simulated Jobs window appears. See: Special Menu.

2. Enter the Job Name.

If a prefix has been entered for the WIP:Discrete Job Prefix profile option, the automatic sequence generator generates a default job name. This name can be overwritten. See: Work in Process Profile Options.

The following fields are defaulted as follows:

Class: If a default accounting class can be found, it is used. If one cannot be found, you must assign an accounting class to the job in the Discrete Jobs window. See: WIP Accounting Class Defaults and Discrete Accounting Classes.

Status: The status defaults to Unreleased. See: Discrete Job Statuses.

Note: The above defaults can be changed using the Discrete Jobs window. See: Defining Discrete Jobs Manually

3. Enter a job Description.

Descriptions can be used to identify jobs on standard reports. They can be up to 240 characters of alpha numeric text. They are optional.

4. Optionally, enter the a descriptive flex value for the job. See: Setting Up Descriptive Flexfields.

5. Save your work.

Note: Values for the following fields are derived or defaulted but can be changed using the Discrete Jobs window. See: Defining Discrete Jobs Manually

MRP Net Quantity: Derived from the job start quantity.

Supply Type: Defaults to Based on Bill. See: Supply Types.

Firm Planned option: Defaults to off (not automatically firmed).

Completion Subinventory and Locator: For jobs with routings, defaults from the routing.

Lot Number: For lot controlled job assemblies, defaults based on how the WIP Default Lot Number Type parameter is set. See: Backflush Default Parameters.

You can also use the Discrete Jobs window to enter values for optional fields: Demand Class, Project, Task, Schedule Group, Build Sequence, and Production Line.

   To view simulated job operations:

• Choose the Operations button. The Operation window appears displaying the job's operations. You can optionally view the components required at a selected operation using the Components button. See: Viewing Job and Schedule Operations.

   To view simulated component requirements:

• Choose the Components button. The Material Requirements window appears and the job's components are displayed. See: Viewing Component Requirements and Viewing Component ATP Information.

Attention: When no routing exists, all components default to operation sequence of 1.
