  SAP Error Message:
  WG040 Requested doc. cat. & not allowed. External req. no. &, mat. no. &
  
  Meaning / Cause:
  This error occurs in the Goods Receipt for Purchase Order process (usually in transaction MIGO or related MM transactions) when the requested document category (doc. cat.) is not allowed for the given external requisition number and material number combination.
  In other words, the system is trying to post a goods receipt or related document with a document category that is not permitted for the referenced purchase requisition or material. This can happen if:
  
  The document category (e.g., 'F' for invoice, 'G' for goods receipt) is not valid for the purchase requisition or purchase order item.
  The external requisition number (purchase requisition number) and material number combination does not allow the requested document category.
  There might be a mismatch or inconsistency in the document flow or configuration.
  The material or purchase requisition is blocked or restricted for the requested document category.
  
  
  Where it occurs:
  
  During goods receipt posting (MIGO, MB01, etc.)
  When referencing a purchase requisition or purchase order in the goods movement.
  In procurement and inventory management processes.
  
  
  Possible Causes in Detail:
  
  Incorrect Document Category: The document category entered or defaulted in the transaction is not allowed for the referenced purchase requisition or material.
  Configuration Issue: The document category is not maintained or allowed in the customizing for the movement type or document type.
  Purchase Requisition Status: The purchase requisition might be in a status that does not allow the requested document category.
  Material Master Data: The material master settings might restrict certain document categories.
  External Requisition Number: The external requisition number might be incorrect or not linked properly to the material or document category.
  
  
  Solution / How to Fix:
  
  
  Check Document Category:
  
  Verify the document category you are trying to post. For example, in MIGO, check the document category (Goods Receipt, Invoice, etc.) and ensure it is correct for the transaction.
  
  
  Verify Purchase Requisition and Material:  
  
  Check the purchase requisition number and material number for correctness.
  Ensure the purchase requisition is released and valid.

  Check Customizing Settings:  
  
  Go to SPRO ? Materials Management ? Inventory Management and Physical Inventory ? Movement Types ? Define Movement Types.  
  Verify if the movement type and document category combination is allowed.

  Check Material Master:  
  
  Verify if the material master has any restrictions or special procurement types that might restrict the document category.
  
  
  
  Check Purchase Requisition Status:  
  
  Use transaction ME53N to check the status of the purchase requisition.
  Ensure it is not blocked or deleted.
