  SAP Error Message:
  
  WY026 - Supplier & does not exist
  
  Cause:
  This error occurs when the system cannot find the specified supplier (vendor) master record in the system. It typically happens during procurement or invoice processing when the vendor number entered does not exist or is not valid in the current company code or purchasing organization context.
  Common reasons include:  
  
  The vendor number entered is incorrect or mistyped.  
  The vendor master record has not been created or is inactive.  
  The vendor is not extended to the relevant company code or purchasing organization.  
  The vendor master data is locked or blocked for transactions.
  
  
  Solution:
  
  
  Verify Vendor Number:
  
  Check the vendor number entered for any typing errors.
  
  
  Check Vendor Master Data:  
  
  Use transaction XK03 (Display Vendor) or MK03 (Display Vendor Purchasing) to verify if the vendor exists.  
  Confirm that the vendor is created and active in the relevant company code and purchasing organization.
  
  
  
  Extend Vendor Master Data:
  
  If the vendor exists but is not extended to the required company code or purchasing organization, use XK01 or XK02 to extend the vendor master data accordingly.
  
  
  Check Vendor Status:
  
  Ensure the vendor is not blocked for posting or marked as inactive.
  
  
  Authorization Check:
  
  Verify that you have the necessary authorizations to access or use the vendor master data.
  
  
  Data Consistency:
  
  If the vendor master data was recently created or changed, ensure that the data has been properly saved and replicated if applicable.
