• What is the cause and solution for SAP error message WU771 - Entry of new plant groups: Subsequent processing already started ?

  The SAP error message WU771 ("Entry of new plant groups: Subsequent processing already started") typically occurs when you attempt to create or modify plant groups in the system while there is already an ongoing process that is dependent on those plant groups. This can happen in various scenarios, such as during the creation of new materials, changes in master data, or when there are open transactions that reference the plant groups.
  
  Cause:
