• What is the cause and solution for SAP error message PSB_API_MSGCL102 - Network &1 locked; you cannot perform inheritance operations ?

  The SAP error message PSB_API_MSGCL102 indicates that a network (or a project network) is locked, which prevents you from performing inheritance operations. This typically occurs in the context of Project System (PS) where you are trying to inherit certain attributes or settings from a superior object (like a project) to a subordinate object (like a network).
  Cause:
  
  
  Network Locking: The network is locked for editing, which can happen for various reasons, such as:
  
  The network is currently being processed by another user or transaction.
  The network is in a status that does not allow changes (e.g., completed or closed).
  There are background jobs or processes that are currently using the network.
  
  
  
  Authorization Issues: The user may not have the necessary authorizations to perform the inheritance operation on the locked network.
  
  
  Solution:
  
  
  Check Network Status: Verify the status of the network. If it is in a status that does not allow changes, you may need to change its status or wait until it is released.
  
  
  Unlock the Network: If the network is locked by another user or process, you may need to:
  
  Wait for the other user to finish their work.
  Check for any background jobs that might be locking the network and wait for them to complete.
  If necessary, consult with your SAP Basis team to unlock the network if it is stuck.
  
  
  
  Review Authorizations: Ensure that you have the necessary authorizations to perform the operation. You may need to contact your SAP security team to verify your permissions.
  
  
  Use Transaction Codes: You can use transaction codes like SM12 to check for locks on the network and SM21 to review system logs for any related issues.
  
  
  Retry the Operation: Once the network is unlocked and you have the necessary permissions, try performing the inheritance operation again.
  
  
  Related Information:

  CN22 (Change Network)
