• What is the cause and solution for SAP error message /SCWM/GM774 - Posting only possible with positive quantity ?

  The SAP error message /SCWM/GM774: Posting only possible with positive quantity typically occurs in the context of the Extended Warehouse Management (EWM) module when attempting to post a goods movement with a negative quantity. This error indicates that the system does not allow posting a goods movement (such as a goods receipt, goods issue, or transfer posting) with a negative quantity, which is often not valid in the context of inventory management.
  Causes:
  
  Negative Quantity Attempt: The most common cause is that the user is trying to post a goods movement with a negative quantity, which is not allowed in certain scenarios.
  Incorrect Document Type: The document type being used may not support negative postings.
  Configuration Issues: There may be configuration settings in the EWM or Inventory Management that restrict negative postings.
  Stock Type Restrictions: Certain stock types (like unrestricted stock) may not allow negative postings.
  
  Solutions:
  
  Check Quantity: Ensure that the quantity being posted is positive. If you intended to reduce stock, you may need to perform a goods issue instead of a negative posting.
  Review Document Type: Verify that the document type you are using allows for the type of posting you are attempting. If you need to post a negative quantity, consider using a different document type that supports this.
  Configuration Review: Consult with your SAP EWM or Inventory Management configuration team to review the settings related to goods movements and negative postings. Adjustments may be needed to allow for specific scenarios.
  Use Correct Transactions: If you need to reduce stock, use the appropriate transaction codes for goods issues or stock transfers that are designed for such operations.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on posting goods movements in EWM.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this error or provide additional context.
  Transaction Codes: Familiarize yourself with relevant transaction codes in EWM, such as /SCWM/GR for goods receipts and /SCWM/GO for goods issues.
  User Training: Ensure that users are trained on the correct procedures for posting goods movements to avoid common errors.
  
  If the issue persists after checking these aspects, it may be beneficial to engage with your SAP support team or consult with an SAP expert for further troubleshooting.
