Ins lot creation at componenyt Good receipt (Ins type 01)

Hi

We are doing the good receipt of external procured items and for a material (A) and a unique batch (B) if Good receipts are at different point of time still we generate inspection lot/sample plan only at first good receipt. There is no new insp lot/sample plan generated whenever was the last good receipt.This is standard SAP.

Now we want that if last good receipt for a mareial (A) and batch (B) was older than one year then a new insp lot/sample plan should be generated( Since vendor is supplying the same batch for which we had good receipt one year before).

Please suggest how to map it. Is there any user exit to it?

Thanx
