• What is the cause and solution for SAP error message /SCWM/GM030 - GR not allowed from material to GR-HU. Pack first, then post ?

  The SAP error message /SCWM/GM030 with the description "GR not allowed from material to GR-HU. Pack first, then post" typically occurs in the context of the Extended Warehouse Management (EWM) module when trying to perform a Goods Receipt (GR) directly into a Handling Unit (HU) without first packing the material into that HU.
  Cause:
  This error arises because the system requires that materials be packed into a Handling Unit before they can be posted to the Goods Receipt. The process is designed to ensure that all items are properly packed and accounted for in the warehouse management system before they are officially received.
  Solution:
  To resolve this error, you need to follow these steps:
  
  
  Pack the Material:
  
  Navigate to the packing transaction in SAP EWM.
  Select the material that you want to pack.
  Create a Handling Unit (HU) and pack the material into it.
  
  
  
  Post the Goods Receipt:
  
  Once the material is packed into the HU, you can proceed to post the Goods Receipt.
  Use the appropriate transaction code (e.g., /SCWM/GR or similar) to post the GR against the packed HU.
  
  
  
  Related Information:
  
  Handling Units (HUs): HUs are used in EWM to manage and track inventory. They can represent a single item or a collection of items packed together.
  Packing Process: The packing process in EWM involves creating HUs and assigning materials to them. This is crucial for inventory management and logistics processes.
  Transaction Codes:
  
  /SCWM/PR - Packing
  /SCWM/GR - Goods Receipt
  
  
  Configuration Settings: Ensure that your EWM system is properly configured to handle packing and goods receipt processes. This includes settings for handling units, packaging materials, and inventory management.
  
  Additional Tips:
  
  Always check the status of the material and the HU before attempting to post a GR.
  Review the documentation for your specific version of SAP EWM, as there may be variations in the process or additional settings required.
