  Cause:
  
  Missing Customer Master Data: The customer number you are trying to use has not been created in the KNA1 table, which stores general data for customers.

  Solution:
  
  Check Customer Number: Verify that the customer number you are using is correct. Ensure there are no typographical errors.
