What it means by retro active rebates and how there are configured. Please also explain how rebates settlement will happen...
Retroactive Rebate Processing:
You can create rebate agreement for which the validity period start date lies in the past. The system takes in to account all the rebate relevant billing documents that were created between the validity start date & the date you created the rebate agreement. In addition to the credit memo request, the system creates a correction sales doc (type B2) automatically for this amount.
Create the rebate agreement in the usual way. The system recognizes that the rebate agreement is retroactive.
retro active rebates are those for which the rebates are not calculated at the time of Invoice. Say you created the rebate agreement today and then you want to give the rebates for the already invoiced ones. Those are called retro active rebates. You can see in the rebate cond record at the bottom as retroactive once you created the record. The prerequisites are the Sal Org, payer and billing type are to be made active for reabtes earlier itself.
