  SAP Error Message:
  
  WT301 - Please enter customer
  
  Cause:
  The error message WT301 occurs in SAP when the system expects a customer number to be entered but it is missing or not provided in the relevant transaction or process. This typically happens in scenarios involving:
  
  Withholding Tax (WHT) configuration or processing where the system requires a customer/vendor to be specified.
  Transactions related to Withholding Tax (WT) where the customer field is mandatory.
  Master data or document entry where the customer field is mandatory but left blank.
  
  In other words, the system is prompting you to enter a valid customer number because it is required for the process to continue.
  
  When does it occur?
  
  During Withholding Tax (WHT) document posting or processing.
  When creating or changing documents that involve withholding tax and the customer field is empty.
  In FI (Financial Accounting) or SD (Sales and Distribution) modules where customer data is mandatory for tax determination.

  Check the Configuration:
  
  Verify the withholding tax configuration to ensure that the system is correctly set up to require or not require a customer.
  In transaction codes like OBWT (Withholding Tax Configuration), check if the customer field is mandatory for the relevant withholding tax type.
  
  
  
  Review the Document or Transaction:
  
  If you are posting a document, ensure that the customer field is filled.
  If the process involves vendor/customer withholding tax, ensure the correct party is entered.
  
  
  
  Master Data Maintenance:
  
  Check the customer master data (transaction XD03 or FD03) to confirm the customer exists and is active.
  Ensure the customer has the necessary tax information maintained.
