  The SAP error message /SAPAPO/PPM_GENERATE202 indicates that there is an attempt to create a new input row in the PP/DS (Production Planning/Detailed Scheduling) planning table, but a row with the same key already exists. This typically occurs during the planning run when the system tries to generate a new planning object (like a production order or a planned order) that conflicts with an existing one.
  Cause:

  Concurrent Planning Runs: If multiple planning runs are executed simultaneously, they may attempt to create the same entries.
  
  Solution:
  
  Check Existing Entries: Review the planning table for existing entries that match the key of the new entry being created. You can use transaction codes like /SAPAPO/PPM or relevant reports to check for duplicates.
  Adjust Planning Parameters: Ensure that the planning parameters are set correctly to avoid generating duplicate entries. This may involve reviewing the planning strategy, lot sizing, or other relevant settings.
  Data Cleanup: If there are inconsistencies in the data, perform a cleanup. This may involve deleting or archiving old or unnecessary entries in the planning table.
  Run Planning in Sequence: If concurrent planning runs are an issue, consider scheduling them to run sequentially to avoid conflicts.
