Hi Finance experts,
We have added Identity Type (Customer/Supplier type) and Identity(Customer ID/Supplier ID) to voucher_row_tab via a Modification.

Now there is a requirement to modify External File Templates STDVOU/STDVOU2 to update above values.
I believe this is a Modification but I would like to know
1. Is this a complex modification requires changes in multiple places?
2.Is it a good practice to change STDVOU/STDVOU2 templates?
3. Do we have any other alternative options like Configuration instead of a Modification to achive this?
