  The SAP error message /SAPNEA/J_SC028 System error: Data could not be locked typically indicates that there is an issue with data locking in the SAP system. This can occur in various scenarios, such as when multiple users or processes are trying to access or modify the same data simultaneously, leading to a conflict.
  Causes:

  Configuration Issues: Incorrect configuration settings in the SAP system related to locking mechanisms.
  
  Solutions:
  
  Check Lock Entries: Use transaction code SM12 to check for existing lock entries. If you find locks that are no longer needed, you can delete them (if you have the necessary authorizations).
