• What is the cause and solution for SAP error message W_CB172 - Document &1 is not a supplier list ?

  SAP Error Message:
  
  W_CB172 Document &1 is not a supplier list
  
  Cause:
  This warning message occurs when you try to process or use a document in a context where a supplier list (also known as a vendor list) is expected, but the document you referenced is not recognized as such. In SAP, a supplier list is a specific type of document that contains a list of vendors, often used in procurement or invoice verification processes.
  For example, this error can appear if you try to use a document number that is not assigned or created as a supplier list in transactions or programs that require a supplier list document.
  
  When does it typically occur?
  
  When you enter a document number in a field expecting a supplier list document.
  When running reports or processes that require a supplier list but the document provided is of a different type (e.g., a purchase order, invoice, or other document).
  During invoice verification or vendor evaluation processes where supplier lists are used.
  
  
  Solution:
  
  
  Check the Document Type:
  
  Verify that the document number you entered is indeed a supplier list.
  Use transaction codes like ME51N, ME52N, or ME53N (Purchase Requisition) or other relevant transactions to check the document type.
  Alternatively, check the document in the database or via report to confirm its type.
  
  
  
  Use the Correct Document:
  
  If the document is not a supplier list, find the correct supplier list document number.
  If you intended to use a supplier list, create one using the appropriate transaction (e.g., supplier list creation transactions or vendor master data maintenance).
  
  
  
  Correct the Process Flow:
  
  Ensure that the process or program you are running is supplied with the correct document type.
  If you are customizing or developing, add validation to prevent incorrect document types from being used.
  
  
  
  Consult SAP Documentation or Support:
  
  If unsure about the document types and their usage, refer to SAP Help Portal or your organization's SAP documentation.
  Check OSS notes or SAP Knowledge Base Articles for any known issues related to this message.
