India GST - How to get HSN/SAC code defaulted on IL Tax Details form?

Hi Experts,

I have a question on how to get HSN/SAC code defaulted on India Tax Details - is there a way to get these defaulted or a way to select on transaction screens?

The following are my questions -

1. I set up a SAC code at SAC code for Third Party Level and attached to the supplier, this gets defaulted, but I can't get HSN code defaulted as I don't see any code for it. Which code I have to use to get HSN codes defaulted? We don't use Inventory.

2. There could be a possibility of a supplier providing multiple products with different HSN/SAC codes (multiple tax rates), and I don't see a document explaining how to tax these transactions (other manual intervention). Any idea how this can be handled, we only use Purchasing Categories.
