Data extension Form for Digitally Signed Billing Documents (Portugal)

[rubensantos]

I need to extend the data source FDP_V3_BD_STANDARD_GLO_PT_SRV in order to add the outbound delivery number.

I have already tried to use the custom fields app, I tried to find this data source in the data source extension tab but I wasn't able to find it. I then tried to create a custom field (then i would apply a custom logic to it) under the Sales: Billing Document (SD_BILLINGDOC) business context but I was not able to find usage for the billing form templates.

Can you please help me find a way to solve this?

Thank you in advance

Did you find a solution to this? I need to update the invoice with 3 extra fields that are not available in the Data Model FDP_V3_BD_STANDARD_GLO_PT.
