  The SAP error message DHCDC_CDS050 indicates that a record in a queue was not locked, which typically occurs in the context of data processing or when working with change documents in SAP. This error can arise due to various reasons, including concurrent access issues, system configuration problems, or transaction management issues.
  Causes:
  
  Concurrent Access: Multiple users or processes may be trying to access or modify the same record simultaneously, leading to a locking conflict.
  Lock Timeout: The system may have a lock timeout configured, and if a record is not locked within the specified time, this error can occur.

  Solutions:
  
  Check for Concurrent Users: Investigate if multiple users are trying to access the same record. If so, coordinate with users to avoid simultaneous access.
  Increase Lock Timeout: If applicable, consider increasing the lock timeout settings in the SAP system to allow more time for locks to be acquired.

  Review Configuration: Check the configuration settings related to change documents and locking mechanisms to ensure they are set up correctly.
