Payment template for employees as suppliers

Hi

I'd need your support to create a payments template for both suppliers in Payabales and employees as suppliers (created via HR API), there's a specific conditions that is not working

The template is a fixed position based, with the following template:

Application: Payments

Template type: eText - Outbound

Data Definition: Oracle Payments Funds Disbursement Payment Instruction Extract 1.0

Template Fles: eText

The issue I have is when the template is trying to return the VAT number, because the HR API does not inform the ap_suppliers.num_1099 field - But I can obtain the Vat Registration Number

However, with an IF condition I am not able to obtain the Vat Number, would you know why this condition is not working?
