• What is the cause and solution for SAP error message CY090 - The planning table is already active. Recursive calling up is not allowed ?

  The SAP error message CY090 ("The planning table is already active. Recursive calling up is not allowed") typically occurs in the context of SAP's Advanced Planning and Optimization (APO) module, particularly when dealing with planning tables in the Supply Chain Management (SCM) environment. This error indicates that a planning table is already in use, and the system does not allow a recursive call to the same planning table.
  Cause:
  
  
  Active Planning Table: The primary cause of this error is that the planning table you are trying to access is already active in another session or process. This can happen if:
  
  A user is already working on the planning table.
  A background job is currently processing the planning table.
  There is a session that has not been properly closed or terminated.
  
  
  
  System Configuration: In some cases, the system configuration may not allow multiple accesses to the same planning table simultaneously.
  
  
  Solution:
  
  
  Check Active Sessions: 
  
  Verify if there are any active sessions or users currently using the planning table. You can do this by checking the transaction codes like SM50 (Process Overview) or SM66 (Global Process Overview) to see if the planning table is in use.
  
  
  
  Terminate Unused Sessions: 
  
  If you find any sessions that are no longer needed, you can terminate them. Be cautious when doing this to avoid disrupting other users.
  
  
  
  Wait for Completion: 
  
  If a background job is running, you may need to wait for it to complete before attempting to access the planning table again.
  
  
  
  Review Configuration: 
  
  If this issue occurs frequently, review the configuration settings for the planning table to ensure that it allows for the desired level of concurrency.
  
  
  
  Restart the Transaction: 
  
  Sometimes, simply restarting the transaction or logging out and back into the system can resolve temporary issues.
  
  
  
  Contact Support: 
  
  If the problem persists and you cannot identify the cause, consider reaching out to your SAP support team or consulting SAP Notes for any known issues related to this error.
  
  
  
  Related Information:
