• What is the cause and solution for SAP error message W_CB171 - Document &1 is not a customer list ?

  SAP Error Message:
  
  W_CB171 Document &1 is not a customer list
  
  Cause:
  This warning message occurs when you try to process or reference a document in a function or transaction that expects a customer list document type, but the document number (&1) you entered or selected is not classified as a customer list in the system.
  In SAP, certain processes or reports require a document to be of a specific type (e.g., customer list, vendor list, etc.). If the document you provide does not match the expected type, the system issues this warning.
  
  When does it typically occur?
  
  When running reports or transactions related to customer master data or customer lists.
  When trying to use a document number in a process that expects a customer list document but the document is of a different type (e.g., a sales order, delivery, or other document).
  During data upload or batch input sessions where document types are validated.
  
  
  Solution:
  
  
  Verify the Document Number:
  
  Check the document number (&1) you entered.
  Confirm that it is indeed a customer list document.
  You can do this by checking the document type or the transaction where the document was created.
  
  
  
  Use the Correct Document:
  
  If you intended to use a customer list, ensure you select or enter the correct document number that corresponds to a customer list.
  If you mistakenly used a different document type, correct it.
  
  
  
  Check Document Type Configuration:
  
  If you are a system administrator or consultant, verify the document type settings in the customizing (SPRO) under the relevant module (e.g., SD, FI, or CRM).
  Ensure that the document types are correctly defined and assigned.
  
  
  
  Review the Process or Transaction:
  
  Confirm that the transaction or report you are running is appropriate for the document type.
  If you are unsure, consult SAP documentation or your functional consultant.
  
  
  
  
  Additional Information:
  
  The message class W_CB171 is related to customer master or customer list processing.
  This is a warning message (W), so the system may allow you to continue, but the result might not be as expected.
  If this message appears during a custom program or enhancement, check the logic that validates document types.
  
  
  Example:
  If you are running a report that requires a customer list document and you enter a sales order number instead, the system will issue this warning because the sales order is not a customer list.
  
  If you need more specific guidance, please provide the transaction code or process where this message appears.
