Generating Variant Process Plans from a Generic Sequence
You can manage multiple variant process plans using a single generic sequence, eliminating the need to create separate sequences for each variant. In the generic process plan, you can define a sequence that references operation numbers instead of variant-specific operations. For example, you set the branching operation to 10 and the return operation to 30. These numbers act as labels that the system uses to identify the start and end points of the sequence. When you generate a variant process plan, the system resolves these labels to the correct operations for that variant process plan.
Benefits
• This approach ensures consistency, efficiency, and easier maintenance.
• You define the sequence once at the generic level, and any updates you make automatically apply to all variants.

You must set the value of the Allow Operations And Standard Procedures With Same Label Number preference to Yes to enable multiple operations to share the same label number.

Understanding Carry-Forward Behavior
• Set the value of the Allow Operations And Standard Procedures With Same Label Number preference to Yes.
• Assign expressions to operations within the generic sequence. These expressions determine which operations are carried forward when generating a variant process plan.
• Assign the same label number to different operations to define branching and return points.
• Synchronize after updates to ensure changes reflect in the discrepancy report.
Example
1. Set the value of the Allow Operations And Standard Procedures With Same Label Number preference to Yes.
2. Assign expression 120 to Operation 1 in Sequence 1. The label number of Operation 1 is 0010.
3. Assign expression 108 to Operation 2 in Sequence 1. The label number of Operation 2 is 0020.
4. Assign expressions 120 and 108 to Operation 3 in Sequence 1. The label number of Operation 3 is 0030.
5. Change the label number of Operation 2 to 0010. Now, both the operations have the same label number.
6. Provide label number 0010 for branching operation attribute of generic sequence.
7. Provide label number 0030 for return operation attribute of generic sequence.
8. Generate the variant process plan for variant BOM having variant specification as 120.
Only Operation 1 and Operation 3 are carried forwarded. Operation 2 is excluded because its expression does not match.
The branching and return attribute values for the generic sequence are also carry forwarded.
Synchronize Label and Sequence Changes in Generated Plans
After you update branching operation, return operation, or label numbers on the generic process plan, synchronize generated variant plans and review sequence attribute changes in the discrepancy report.
Prerequisites
• You have a generated variant process plan linked to a generic process plan.
• You have permissions to check in changes and to run synchronization.
Procedure
1. Open the generic process plan and edit the sequence. Update branching operation and return operation values. Check in the generic process plan.
2. Open the generated variant process plan and select Synchronize.
3. Review the Discrepancy Report. The report shows sequence attribute changes for branching operation and return operation, including source and target values.
4. Apply the updates and complete synchronization. Once the process is complete, the generated plans reflect updated sequence label values. The discrepancy report captures these changes and serves as an audit of the changes made.
