• 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:
  
  Ongoing Processes: The most common cause of this error is that there are ongoing processes (like material master data changes, inventory management transactions, etc.) that are already using the plant groups you are trying to modify or create.
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. If a process is already using the plant group, the system will not allow changes to ensure data integrity.
  Batch Jobs: Sometimes, batch jobs or background processes may be running that are related to the plant groups.
  
  Solution:
  
  Check for Ongoing Processes: Identify if there are any ongoing processes that are using the plant groups. You can do this by checking transaction logs or using transaction codes like SM12 (to check for locks) or SM37 (to check for background jobs).
  Wait for Completion: If you find that there are ongoing processes, you may need to wait until they are completed before attempting to create or modify the plant groups again.
  Release Locks: If you have the necessary authorizations, you can release locks using transaction SM12, but be cautious as this may lead to data inconsistencies if the processes are still running.
  Consult with Basis Team: If you are unsure about the processes or locks, it may be helpful to consult with your SAP Basis team or system administrator for assistance.
  Review Custom Code: If there are custom programs or enhancements that interact with plant groups, review them to ensure they are not causing the issue.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  SM12: To view and manage locks.
  SM37: To monitor background jobs.
  SE11: To check data dictionary objects related to plant groups.
  
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Documentation: Review SAP documentation for plant group management and related processes to understand the dependencies and workflows involved.
  
  By following these steps, you should be able to resolve the WU771 error and successfully manage plant groups in your SAP system.
