• What is the cause and solution for SAP error message /CWM/QM004 - Only CW or non-CW materials are allowed ?

  The SAP error message /CWM/QM004: Only CW or non-CW materials are allowed typically occurs in the context of the SAP Extended Warehouse Management (EWM) system, particularly when dealing with materials that are classified as either "CW" (Controlled Warehouse) or "non-CW" materials. This error indicates that there is a mismatch in the type of materials being processed in a specific operation, such as during goods receipt, goods issue, or inventory management.
  Cause:
  
  Material Classification: The error arises when an operation is attempted with a material that does not match the expected classification (either CW or non-CW). For example, if the system expects a CW material but receives a non-CW material, or vice versa.
  Configuration Issues: There may be configuration settings in the EWM or the material master that are not aligned with the expected material types.
  Inconsistent Data: The material master data may have inconsistencies, such as incorrect settings for the material type or warehouse management views.
  
  Solution:
  
  
  Check Material Master Data: Verify the material master data for the materials involved in the transaction. Ensure that the materials are correctly classified as CW or non-CW.
  
  Go to transaction MM03 to view the material master and check the relevant views (e.g., Basic Data, Warehouse Management).
  
  
  
  Review Configuration Settings: Check the configuration settings in the EWM system to ensure that the settings for CW and non-CW materials are correctly defined.
  
  This may involve reviewing the settings in the Customizing (SPRO) for EWM and ensuring that the warehouse process types and material types are correctly configured.
  
  
  
  Adjust the Transaction: If the transaction is being performed incorrectly (e.g., trying to process a non-CW material in a CW-specific process), adjust the transaction to use the correct material type.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to this error message for any specific guidance or updates that may be relevant to your version of SAP.
