  WSTRN016 - Specify an article number
  
  Cause:
  The error message WSTRN016 occurs when the system expects an article number (material number) to be entered but it is missing or not specified in the transaction or process you are performing. This typically happens in scenarios related to warehouse management, inventory transactions, or when handling goods movements where the article/material number is mandatory.

  Solution:
  
  
  Enter the Article Number:
  
  Make sure to specify a valid article/material number in the required field. The article number should correspond to a material master record in the system.

  Check Customizing/Configuration:
  
  If the error occurs unexpectedly, check the warehouse management or inventory management configuration to ensure that the system is not incorrectly expecting an article number where it should not.
  
  
  User Training:
  
  Train users to always enter the article/material number when required and to verify the correctness of the data before saving or posting.
