Control of Purchase reqs in SNP run

    Gurus,

We are having an issue with huge number of PReqs created every week during the SNP run. I was trying to see if something like ECC where you can say after a certain period group PReqs into a monthly bucket. We want to have PReqs by lot size for 8 weeks and then want to club it into one single PReq/Month.

Any guidance/help will be highly appreciated.

Thanks,

Subash
