• What is the cause and solution for SAP error message CO788 - Function could not be executed because (sub-)network is being processed ?

  The SAP error message CO788 indicates that a function could not be executed because a (sub-)network is currently being processed. This typically occurs in the context of production orders or network activities in project systems, where certain operations cannot be performed while the system is processing a network or sub-network.
  Cause:
  
  
  Network Processing: The error usually arises when a network or sub-network is being processed by another transaction or user. This could be due to:
  
  A background job that is currently running and processing the network.
  Another user is accessing or modifying the same network.
  A lock on the network due to ongoing operations.
  
  
  
  System Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. If a network is locked for processing, other operations that require access to that network will be blocked, leading to this error.
  
  
  Solution:
  
  
  Wait and Retry: If the network is being processed by another user or job, the simplest solution is to wait until the processing is complete. You can check the status of the network or the background job to see when it will be released.
  
  
  Check Background Jobs: Use transaction code SM37 to check for any background jobs that might be processing the network. If you find a job that is taking too long, you may need to investigate further or contact the person responsible for that job.
  
  
  Identify Locks: Use transaction code SM12 to check for locks on the network. If you find that a lock is held by a user or a process that is no longer active, you may need to release the lock. However, be cautious when doing this, as it may lead to data inconsistencies.
  
  
  Consult with Colleagues: If you are in a collaborative environment, check with your colleagues to see if anyone else is working on the same network or if they have encountered similar issues.
  
  
  System Administrator: If the issue persists and you cannot identify the cause, it may be necessary to involve your SAP Basis team or system administrator to investigate further.
