3730512 - FPAYH-INTAD(Internet address) is empty in the payment file

The user wants to include the Business Partner email address (fields LFB1-INTAD / KNB1-INTAD) in a custom payment format.

However:

• The email node is mapped to FPAYH-INTAD in the payment format.
  
• After executing the payment run and generating the payment file,
• The mapped email node appears empty in the output file.

1. Create or use a custom payment format.
2. Map the email node to FPAYH-INTAD.
3. Execute a payment run to generate the payment medium file.
4. Open the generated file.
5. Observe that the mapped email node contains no value.

• Field FPAYH-INTAD is not populated by the payment program with the Business Partner email.
• It does not reference LFB1-INTAD / KNB1-INTAD.
• Instead, FPAYH-INTAD is intended for a user’s personal email address, not the Business Partner’s email.

1. Do not use FPAYH-INTAD for exporting the business partner email; it refers to a user’s personal email, not the business partner email.
2. Create and enable a customer reference field (ZREF) in the payment mapping structures to carry the business partner email.
3. Use the application Custom Logic, Event ID FBL_EVENT_06 - Payment Medium: Custom Additional Reference Fields (Business Add-In BAdI) to implement your own logic to fill the data into ZREFxx custom reference fields to read the business partner email from LFB1-INTAD/KNB1-INTAD, which will be exported into payment file. 
   For reference: See blog How to export a custom field (e-mail) in the payment file
4. In the custom payment format, map the email node to the ZREF field instead of FPAYH-INTAD.
5. Regenerate the payment file and verify that the email node now contains the business partner email.
