• What is the cause and solution for SAP error message WXP421 - Enter a plan version for "Setup based on plan data" ?

  SAP Error Message:
  
  WXP421 - Enter a plan version for "Setup based on plan data"
  
  Cause:
  This warning message appears in SAP when you are trying to execute a planning or setup transaction that requires a specific plan version to be entered, but the system does not find a valid plan version specified. The message typically occurs in the context of Production Planning (PP) or Demand Management, especially when working with planning versions in Material Requirements Planning (MRP) or Demand Planning.
  The system expects a plan version to be entered because the planning data (such as demand, supply, or production plans) is version-controlled. Without specifying the plan version, the system cannot determine which set of planning data to use.
  
  When does it occur?
  
  When running planning transactions that require a plan version (e.g., MRP run, planning table, or setup based on plan data).
  When the plan version field is left blank or the default plan version is not maintained.
  When the system is configured to use planning versions but none is selected.
  
  
  Solution:
  
  
  Enter a valid plan version:
  
  In the transaction or screen where the message appears, enter the appropriate plan version in the field labeled "Plan Version" or similar.
  The plan version is usually a numeric or alphanumeric code representing a specific planning scenario or version.
  
  
  
  Check and maintain plan versions:
  
  Use transaction OPPR (Maintain Planning Versions) to check existing plan versions.
  If no plan versions exist, create and maintain the necessary plan versions.
  Assign the plan versions to the relevant planning objects (e.g., materials, plants).
  
  
  
  Set a default plan version (optional):
  
  If you want to avoid entering the plan version every time, you can set a default plan version in the customizing settings or user parameters, if applicable.
  
  
  
  Verify configuration:
  
  Ensure that the planning version is properly configured in the system and linked to the relevant planning processes.
  Check if the planning version is active and valid for the planning period.

  Summary:
  
  Cause: No plan version entered where required.

  Additional: Maintain plan versions in customizing and assign them properly.
