• What is the cause and solution for SAP error message CKMLMV030 - Data was changed ?

  The SAP error message CKMLMV030 ("Data was changed") typically occurs in the context of Material Ledger (ML) and is related to the processing of material movements or inventory valuations. This error indicates that the data being processed has been modified after it was initially read, which can lead to inconsistencies or conflicts during the posting process.
  Causes:
  
  Concurrent Updates: The most common cause is that another user or process has changed the data in the database after it was read by the current transaction. This can happen in environments with multiple users or batch processes running simultaneously.
  Data Locking Issues: If the data is locked by another transaction, it may lead to this error when trying to update or post changes.

  Retry the Transaction: Often, simply retrying the transaction after a short wait can resolve the issue, especially if it was caused by a temporary lock or concurrent update.
  Check for Locks: Use transaction codes like SM12 (to check for locks) and SM21 (to check the system log) to identify if there are any locks or issues that need to be resolved.
  Review Change Logs: Check the change logs for the material or related data to see what changes were made and by whom. This can help identify if another user or process is causing the conflict.
  Data Consistency Check: Run consistency checks on the Material Ledger data to ensure that there are no inconsistencies that need to be addressed.
  Consult with Basis Team: If the issue persists, it may be necessary to involve the SAP Basis team to investigate any underlying database issues or performance problems.
