Function documentationHeuristic for Filling of Resource Gaps

 

You can use the heuristic SAP_PI_002 to reduce or even eliminate any gaps between operations on a resource. You do this by reducing the rate, thereby stretching activities either forward or backward, as required.

Note Note

  • You cannot exceed the maximum stretch factor assigned in the Resource Master. If any gap remains even after running the heuristic, you must find other means to close the gap.

  • Once you change the rate of an activity, the changed value is retained even after the rescheduling. You must set the original rate manually, if and when required.

End of the note.

Prerequisites

The following master data is maintained:

  • Location

  • Product

  • Resource

  • PPM and/or PDS for a Production Planning for process industries (PP-PI) scenario

You have activated the business function SCM-APO-PPS, Continuous Production and Multi-Resource Scheduling (SCM_APO_PPDS_PI).

The heuristic has been added to the heuristic profile to be accessible from the Detailed Scheduling Planning Board, Product View, and Product Planning Table. In Customizing, go to Start of the navigation path Advanced Planning and Optimization Next navigation step Supply Chain Planning Next navigation step Production Planning and Detailed Scheduling (PP/DS) Next navigation step Heuristics Next navigation step Maintain Heuristic Profiles End of the navigation path.

Activities

  1. Run transaction /SAPAPO/CDPS0 for the Detailed Scheduling Planning Board.

  2. Select the overall profile SAP001 and planning version 000.

  3. Enter the appropriate resource, location, or product for which the order was created. Choose Execute.

  4. Choose Profiles and select the heuristic profile defined in Customizing. Then choose Copy (Enter) to save the setting.

  5. Select the resource that has operations with gaps to be filled.

  6. Choose Start of the navigation path Functions Next navigation step Heuristic Next navigation step Fill gaps by changing operation duration End of the navigation path to run the heuristic.
