Can we default Tax invoice number & Tax invoice date captured at GRN be flown to ERS Invoice in AP?

Summary:

Hi All,

We are creating AP invoice automatically via ERS(Pay On Receipt program). Since Supplier invoice number and date cannot be defaulted on the ERS invoice Number & date field. We are exploring if Tax invoice number & Tax invoice date which is available at GRN creation page can be used to default the supplier invoice number and Date.

But Tax invoice number & Tax invoice date captured at GRN level is not flowing into ERS invoice, invoice gets created with these two fields as blank.

Can anyone suggest how to default these values on ERS invoice?
