Hello - I wanted to check with regards to e-Invoicing law of India from Procurement perspective.
Currently before the law kicks in on Oct - 2020, we have 3 systems relating to procurement - SAP Ariba, SAP S4 and OpenText. We have a Reference Field where we will input invoice number to trigger processing of payments.
However, once the e-invoicing law kicks in from Oct - 2020;
1) Are we supposed to use IRN# instead of Invoice# to trigger processing of payment?
2) Or we need both IRN# and Invoice#?
3) How about vendors that does not cross the e-invoicing thresholds and not subjected to generate IRN#? We continue to use Invoice# to trigger processing of payments?
