• What is the cause and solution for SAP error message /SCWM/RF_EN771 - Follow-up WT creation failed. Bin &2 locked by &1. Try again? ?

  The SAP error message /SCWM/RF_EN771 indicates that a follow-up Warehouse Task (WT) creation has failed because the bin is locked by another user or process. This typically occurs in the context of warehouse management operations where multiple users or processes may be trying to access or modify the same bin simultaneously.
  Cause:
  
  Bin Locking: The bin is currently locked by another user or process. This can happen if another transaction is in progress that is using the same bin.
  System Configuration: There may be specific configurations in the system that enforce locking mechanisms for certain operations.
  Long-running Transactions: If a transaction takes too long to complete, it may hold the lock on the bin longer than expected.
  
  Solution:
  
  Retry the Operation: Often, simply waiting a moment and trying the operation again can resolve the issue if the lock is temporary.
  Check for Active Processes: Use transaction codes like SM12 (to check for locks) or SM21 (to check system logs) to identify if there are any active processes that are locking the bin.
  Communicate with Users: If you identify that another user is holding the lock, communicate with them to understand if they can release the lock or if they are still actively using the bin.
  Adjust Locking Mechanisms: If this is a frequent issue, consider reviewing the system configuration for locking mechanisms and see if adjustments can be made to reduce contention.
  System Performance: Ensure that the system is performing optimally. Long-running processes can lead to locks being held longer than necessary.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM12 for lock entries, SM21 for system logs, and SLG1 for application logs.
  User Training: Ensure that users are trained on proper warehouse management practices to minimize the chances of locking issues.
  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide patches related to this error message.
  System Monitoring: Implement monitoring tools to keep track of warehouse operations and identify potential bottlenecks or locking issues proactively.
  
  If the problem persists after trying the above solutions, it may be necessary to involve your SAP Basis team or consult SAP support for further assistance.
