ISO20022 Employee Payment File - Adding new fields

Hi,

Reposting to seek some HCM expert help 🙂

We are trying to generate an employee payment file (to pay for employee expenses) using ISO20022. There are few mandatory information that we need to bring into this file as follows;

• Employee Tax ID
• Clearing system member ID
• Branch ID

These refer to employee specific details. I have tried to use ‘Property Fields’ and define these information. However, there is no way to connect those new property fields to ‘Employee payment method’ window. 

1. Does anyone know how we can define new property fields and bring those details into the ISO20022 XML file? OR
2. Is there any alternative method to use to bring in such additional information to ISO20022 XML file?

Thank You
