How To Fix VLBAPI006 - Cross-system lock still exists despite the error

VLBAPI006 - Overview

• Message type: E = Error

• Message class: VLBAPI - Output Texts for Delivery BAPIs

• Message number: 006

• Message text: Cross-system lock still exists despite the error

What causes this issue?

Collected delivery blocks could not be removed jointly, since at least
one lock request could not be guaranteed.
The system therefore tried to reset all previously ensured locks. This
failed for at least one delivery that was distributed to a
decentralized WMS.

System Response

For at least one distributed delivery, the system could not remove the
cross-system lock, and it therefore still exists. The delivery can be
released automatically at the end of the LUW (logical unit of work).

How to fix this error?

The inconsistency is automatically removed when you exit the
transaction.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

VLBAPI006 - Details

• The SAP error message VLBAPI006 indicates that a cross-system lock still exists despite an error occurring in the process. This typically happens in scenarios involving inter-system communication, such as when using the SAP Advanced Business Application Programming (ABAP) or when dealing with distributed systems.
  
  Cause:
  The error can occur due to several reasons, including:
  
  Incomplete Transaction: A transaction that was supposed to release a lock did not complete successfully, leaving the lock in place.
  Network Issues: Communication problems between systems can prevent the proper release of locks.
  System Crashes: If one of the systems involved crashes or is restarted unexpectedly, it may not release the locks it held.
  Long-running Processes: If a process takes too long to complete, it may hold onto locks longer than expected, leading to conflicts.
  
  Configuration Issues: Incorrect configuration of the systems involved in the cross-system communication can lead to locking issues.
