• What is the cause and solution for SAP error message /SCWM/WHO521 - More WTs must be assigned to warehouse order &1 ?

  The SAP error message /SCWM/WHO521 indicates that there are not enough Warehouse Tasks (WTs) assigned to a Warehouse Order (WO) in the Extended Warehouse Management (EWM) module. This error typically occurs when the system expects a certain number of WTs to be associated with a WO, but the current assignment is insufficient.
  Cause:
  
  Insufficient Warehouse Tasks: The Warehouse Order has been created, but the number of WTs assigned to it is less than what is required for processing.
  Configuration Issues: There may be configuration settings in the EWM that dictate the minimum number of WTs required for a WO.
  Manual Assignment Errors: If WTs are manually assigned to a WO, there may have been an oversight in ensuring that the required number of WTs is assigned.
  System Logic: The system may have specific logic that determines how many WTs should be assigned based on the type of operation or the items involved.
  
  Solution:
  
  Check Warehouse Order: Review the Warehouse Order in question to see how many WTs are currently assigned. You can do this through the EWM interface.
  Assign More WTs: If the number of WTs is indeed less than required, you can manually assign additional WTs to the Warehouse Order. This can be done through the EWM transaction for managing WTs.
  Review Configuration: Check the configuration settings in EWM to see if there are any parameters that dictate the minimum number of WTs required for a WO. Adjust these settings if necessary.
  Recreate Warehouse Order: If the WO is not critical, consider deleting and recreating it to ensure that the system generates the appropriate number of WTs.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on managing WTs and WOs in EWM.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in EWM, such as /SCWM/ORDIM for managing warehouse orders and /SCWM/WT for managing warehouse tasks.

  User Roles and Permissions: Ensure that the user has the necessary permissions to create and manage WTs and WOs in the EWM system.
