Activity numbers are also assigned to activities that are not defined
in the financial data tables, but instead exist only in the totals
database. The activity numbers are assigned during the activity display
or when the consolidation of investments is started. When this occurs,
the numbers are locked for only a short interval to prevent
inconsistencies. This is now the case.

• What is the cause and solution for SAP error message G0650 - User &1 is blocking the assignment of activity numbers ?

  The SAP error message G0650 indicates that a user is blocking the assignment of activity numbers in the system. This typically occurs in the context of project management or controlling modules where activity numbers are used to track costs and resources.
  Cause:
  The error message "User &1 is blocking the assignment of activity numbers" usually arises due to one of the following reasons:
  
  User Lock: The user mentioned in the error message has an active session that is currently using or modifying the activity numbers, preventing other users from making changes or assignments.
  Transaction Lock: A specific transaction or process is being executed by the user, which locks the activity numbers for that transaction.
  System Configuration: There may be configuration settings in the system that enforce locking mechanisms for activity number assignments.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  Identify the Blocking User: Check the user ID mentioned in the error message. You can use transaction code SM12 to view and manage user locks in the system.
  Release the Lock: If the user is no longer active or if the session can be safely terminated, you can manually release the lock from transaction SM12. Be cautious when doing this, as it may affect ongoing processes.
  Communicate with the User: If the user is actively working on a task, communicate with them to understand if they can complete their work or if they can release the lock.
  Check for Long-Running Transactions: Investigate if there are any long-running transactions that might be causing the lock. If necessary, optimize these transactions to reduce locking time.
  Review System Configuration: If this issue occurs frequently, review the system configuration related to locking mechanisms and consider adjusting them if appropriate.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM12 (for user locks), SM21 (for system logs), and ST22 (for dumps) to diagnose issues further.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP's support portal can provide additional insights and solutions.
  User Training: Ensure that users are trained on how to properly manage their sessions and avoid leaving transactions open unnecessarily, which can lead to locking issues.
  
  If the problem persists after following these steps, it may be necessary to involve your SAP Basis team or SAP support for further investigation.
