I got one call regarding free goods its not a REBATE.
When customer buys 100 products with different orders with different dates,Now i want to give discount for that goods what he consumed earlier.
Ex:Day order quantity
10th 10003 30
13th 10004 40
15th 10005 30
Now system automatically give the discount for this products with out using rebate,how can we do that and any configurations done for this.
