  SAP Error Message:
  
  W_CB079 Customer &1 does not exist
  
  Cause:
  This warning message occurs when the system tries to reference a customer number that does not exist in the customer master data. Specifically, the customer number (represented by &1 in the message) is not found in the relevant customer master records (usually in tables like KNA1, KNB1, etc.).
  Common scenarios include:

  Solution:
  
  
  Verify Customer Number:
  
  Check the customer number entered in the transaction or document.
  Ensure it is correct and complete.
  
  
  
  Check Customer Master Data:
