• What is the cause and solution for SAP error message EEWMGBC226 - Parameter &1 was already allocated ?

  The SAP error message EEWMGBC226, which states "Parameter &1 was already allocated," typically occurs in the context of the Extended Warehouse Management (EWM) module. This error indicates that a specific parameter (represented by &1) has already been assigned or allocated to a particular process or object, and therefore cannot be allocated again.
  Cause:
  
  Duplicate Allocation: The most common cause of this error is an attempt to allocate the same parameter (like a storage bin, handling unit, or other resources) to multiple processes or transactions simultaneously.
  Configuration Issues: There may be issues in the configuration of the warehouse management settings that lead to improper handling of allocations.
  Concurrency Issues: If multiple users or processes are trying to allocate the same parameter at the same time, it can lead to this error.
  
  Solution:
  
  Check Allocation Status: Verify the current allocation status of the parameter in question. Ensure that it is not already in use by another process.
  Release the Parameter: If the parameter is indeed allocated, you may need to release it from the current process before attempting to allocate it again.
  Review Configuration: Check the configuration settings in the EWM system to ensure that they are set up correctly and that there are no conflicts.
  Avoid Concurrent Allocations: If multiple users are involved, implement a process to avoid concurrent allocations of the same parameter.
  Consult Logs: Review system logs or transaction logs to identify any specific transactions that may be causing the conflict.
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like /SCWM/PRDI (for product data) or /SCWM/ORDR (for order management) to check the status of allocations.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide patches or updates to resolve underlying issues.
  Documentation: Refer to the SAP EWM documentation for best practices on managing allocations and handling parameters effectively.
