• What is the cause and solution for SAP error message /SCWM/WHO093 - Limit of one WT per WO set for WOs with relevance to material flow system ?

  The SAP error message /SCWM/WHO093 indicates that there is a limitation in the system where only one Warehouse Task (WT) can be created for a Work Order (WO) when it is relevant to the Material Flow System (MFS). This error typically arises in the context of warehouse management processes, particularly when dealing with work orders that are linked to material flows.
  Cause:
  The error occurs due to the configuration settings in the SAP Extended Warehouse Management (EWM) system, specifically related to how work orders are processed in conjunction with warehouse tasks. The limitation is often set to ensure that the system does not create multiple warehouse tasks for a single work order, which could lead to confusion or inefficiencies in the material flow process.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Review Work Order Configuration: Check the configuration settings for work orders in the EWM system. Ensure that the settings align with your operational requirements. If your business process requires multiple warehouse tasks for a single work order, you may need to adjust the configuration.
  
  
  Adjust Warehouse Task Creation Logic: If the limitation is not suitable for your operations, you may need to modify the logic that governs warehouse task creation. This could involve customizing the system to allow for multiple WTs per WO, depending on your specific needs.
  
  
  Check for Existing WTs: Before attempting to create a new warehouse task for a work order, verify if there is already an existing WT associated with that WO. If there is, you may need to complete or cancel the existing WT before creating a new one.
  
  
  Consult SAP Documentation: Review the SAP documentation related to EWM and MFS to understand the implications of this limitation and any potential workarounds or best practices.
  
  
  Engage with SAP Support: If the issue persists or if you require further customization, consider reaching out to SAP support for assistance. They can provide insights based on your specific system configuration and business processes.
