Error while creating an Invoice in SRM

Hi All,

We are on SRM 7.0, ECC 6.0 (Classic scenario).

My SC has been approved and a PO has been created in ECC, I have also created a confirmation against this from SRM which resulted in a GR being created against the PO in ECC.

Now when I am creating an Invoice from SRM, I get the following error messages

1. Please enter tax amount

2. "Term of payment does not exist in target system".

Pl let me know where I need to maintain the payment terms in ECC and do I need to replicate it on SRM side?

Regards
