IBP- Planning Area refresh From Prod to QA

Hi All,

I am looking for experts advice on planning area refresh in QA system wrt Production system. We have 2 tier landscape having QA and Prod tenants only. The ask from Business is to have Production data in QA planning area for some testing purpose.

1. Can we have a new PA in QA system and point the CPI interfaces to this new PA along with the existing interface?

2. Can we have multiple interfaces for Ex Product MD interface pointing to Planning Area 1 and Planning Area 2 in the same IBP system?

3. Is it good approach to delete all existing MD and TD before re loading for a quality data?

your inputs are highly helpful

Regards,

Divya
