  SAP Error Message:
  WJ021 Customer &1 does not exist in the customer master
  
  Cause:
  This warning message occurs when the system tries to reference a customer number (&1) that is not found in the customer master data. Essentially, the customer number you are using in a transaction or process does not exist or is not maintained in the SAP customer master records (transaction codes like XD01/XD02/XD03 or FD01/FD02/FD03).
  Common scenarios include:  
  
  Entering a customer number incorrectly (typo or wrong number).  
  The customer master record has not been created yet.  
  The customer master record exists but is not valid for the company code or sales area you are working in.  
  The customer master record is blocked or deleted.  
  Data inconsistencies or missing synchronization between modules (e.g., SD and FI).
  
  
  Solution:
  
  
  Verify Customer Number:
  
  Check the customer number you entered for correctness. Make sure there are no typos.
  
  
  Check Customer Master Record:
  
  Use transaction codes like:  
  
  XD03 (Display Customer) to check if the customer exists.  
  FD03 (Display Customer Accounting) to check FI customer master data.  
  VD03 (Display Customer Sales) to check sales area data.
  
  
  
  Create Customer Master Record if Missing:
  
  If the customer does not exist, create it using:  
  
  XD01 (Create Customer - General)  
  FD01 (Create Customer Accounting)  
  VD01 (Create Customer Sales Area)
  
  
  
  Check Sales Area and Company Code Assignments:
  
  Ensure the customer master record is maintained for the relevant sales area and company code.
  
  
  Check Customer Block Status:
  
  Verify if the customer is blocked for sales or accounting. Unblock if necessary.
  
  
  Data Consistency:
  
  If the customer master exists but the error persists, check for data inconsistencies or synchronization issues between SD and FI modules.
  
  
  Authorization:
  
  Ensure you have the necessary authorization to access or create customer master data.
