  SAP Error Message:
  WPM_MSG_OFR_PRM_INTG131 Invalid purchasing group &1
  
  Cause:
  This error occurs when the system encounters a purchasing group value that is not valid or not recognized in the context where it is being used. The purchasing group entered or passed to the system does not exist in the SAP master data or is not properly maintained.
  Common scenarios include:  
  
  The purchasing group code is missing or incorrectly entered in a purchase order, contract, or other procurement documents.  
  Integration or interface scenarios where the purchasing group is passed from an external system but does not match any valid purchasing group in SAP.  
  Custom validations or user-exits that check the purchasing group and find it invalid.
  
  
  Solution:
  
  
  Check Purchasing Group Master Data:
  
  Go to transaction OMSG or SPRO ? Materials Management ? Purchasing ? Maintain Purchasing Groups.
  Verify if the purchasing group code (&1 in the message) exists and is active.
  
  
  
  Correct the Purchasing Group in the Document:
  
  If the error occurs during document creation (e.g., Purchase Order), correct the purchasing group field to a valid value.
  
  
  
  Interface/Integration Check:
  
  If the purchasing group is coming from an external system, ensure the mapping is correct and the purchasing group exists in SAP.
  Update or maintain the purchasing group master data if necessary.
  
  
  
  Custom Code or Validation:
  
  Check if there are any user-exits, BADIs, or validations that enforce purchasing group checks.
  Adjust the logic or update the master data accordingly.
  
  
  
  Transport and System Consistency:
  
  If the purchasing group was recently created or changed, ensure the changes are transported properly to the system where the error occurs.
