  SAP Error Message:
  
  WG109 - Customer data missing for customer &
  
  Cause:
  This error occurs when the system tries to process a transaction or function that requires customer master data, but the relevant customer data is missing or incomplete in the system. Specifically, the system cannot find the necessary customer master record or related data for the customer number referenced (represented by & in the message).
  Common scenarios include:
  
  The customer master record does not exist in the system.
  The customer master record exists but lacks required data in certain views (e.g., sales area data, company code data).
  The customer number used in the transaction is incorrect or not maintained.
  Data inconsistencies or incomplete data migration.
  
  
  Solution:
  
  
  Check Customer Master Data:
  
  Use transaction XD03 (Display Customer) or VD03 (Display Customer - Sales Area) to verify if the customer master record exists.
  Confirm that all necessary views (General Data, Company Code Data, Sales Area Data) are maintained properly.
  
  
  
  Maintain Missing Data:
  
  If the customer master record is missing, create it using XD01 or VD01.
  If certain views are missing, maintain them using XD02 or VD02.
  
  
  
  Verify Customer Number:
  
  Ensure the customer number used in the transaction is correct and valid.
  Check for typos or incorrect references in the program or transaction.
  
  
  
  Check Integration Points:
  
  If the error occurs during data transfer or integration (e.g., IDoc processing, batch jobs), verify that the customer master data is correctly replicated and available in the target system.
  
  
  
  Review Custom Code or Enhancements:
  
  If the error arises from custom developments or user exits, check the logic that fetches or validates customer data.
  
  
  
  Data Consistency Checks:
  
  Run consistency reports or tools to identify and fix incomplete or inconsistent customer master data.
