• What is the cause and solution for SAP error message >6401 - Correspondence not sent to customer - therefore no display ?

  The SAP error message 6401 ("Correspondence not sent to customer - therefore no display") typically occurs in the context of the SAP system when trying to display correspondence (such as invoices, statements, or other documents) that has not been sent to the customer. This can happen in various modules, including Financial Accounting (FI) or Sales and Distribution (SD).
  Cause:
  
  Correspondence Not Generated: The correspondence document has not been generated or processed for the customer.
  Incorrect Configuration: The configuration settings for correspondence types may not be set up correctly.
  Customer Master Data: The customer master data may not have the necessary settings for correspondence.
  Document Status: The document you are trying to display may not have been finalized or may be in a status that prevents it from being sent.
  Output Determination: The output determination procedure may not be correctly configured, leading to the correspondence not being generated.
  
  Solution:
  
  
  Check Correspondence Generation:
  
  Verify if the correspondence has been generated for the specific document. You can do this by checking the output logs or the relevant transaction (e.g., VF03 for billing documents).
  If it has not been generated, you may need to manually trigger the correspondence generation.
  
  
  
  Review Configuration:
  
  Check the configuration settings for the correspondence type in the relevant module (FI or SD). Ensure that the output type is correctly defined and linked to the appropriate forms and conditions.
  For FI, you can check the configuration in transaction SPRO under Financial Accounting > Accounts Receivable and Accounts Payable > Correspondence > Define Correspondence Types.
  
  
  
  Customer Master Data:
  
  Review the customer master data to ensure that the correspondence settings are correctly maintained. Check the communication methods and ensure that the customer is set up to receive correspondence.
  
  
  
  Document Status:
  
  Ensure that the document you are trying to display is in a status that allows for correspondence to be sent. If the document is incomplete or in a draft status, it may not be eligible for correspondence.
  
  
  
  Output Determination:
  
  Check the output determination procedure to ensure that the correct output type is being triggered for the document. You can do this in transaction NACE for the relevant application area.
