  The SAP error message "LL001 Data determination for warehouse monitor object &1 already running" typically occurs in the context of the Warehouse Management (WM) module when there is an attempt to execute a data determination process that is already in progress for a specific warehouse monitor object. This can happen in scenarios where multiple users or processes are trying to access or update the same data simultaneously.
  Cause:
  
  Concurrent Execution: The most common cause of this error is that the data determination process for the specified warehouse monitor object is already being executed by another user or process.

  Check Running Processes: Use transaction codes like SM66 (Global Work Process Overview) or SM50 (Work Process Overview) to check if there are any long-running processes related to the warehouse monitor object. If you identify a stuck process, you may need to investigate further or terminate it if appropriate.
