  SAP Error Message:
  
  W_CB080 - Enter a supplier
  
  Cause:
  This warning message appears when a supplier (vendor) is required but has not been entered in a transaction or a specific field. Typically, this happens in procurement-related processes such as purchase orders, invoice verification, or other supplier-related postings where the system expects a vendor to be specified.
  
  When does it occur?
  
  During creation or processing of purchase documents (e.g., Purchase Orders, Invoices).
  When a transaction requires a supplier/vendor but the field is left blank.
  In custom or standard SAP screens where supplier data is mandatory.
  
  
  Solution:
  
  Enter a valid supplier/vendor number in the required field.
  If you do not know the supplier number, use the search help (F4) to find and select the correct supplier.
  Ensure that the supplier master data exists and is active in the system.
  If the supplier is new, create the supplier master record first (transaction code XK01, FK01, or MK01 depending on the purchasing organization).
  Check if the field is mandatory due to configuration or user-exit enhancements; if so, ensure compliance.
  
  
  Additional Information:
  
  Transaction Codes: ME21N (Create Purchase Order), MIRO (Enter Incoming Invoice), etc.
  Supplier Master Data: Maintain via XK01/XK02/XK03 or vendor master transactions.
