Generate Bulk PO/Requisitions by Regular Vendor

[former_member840815]

Hi Experts,
I would like to optimise my production of POs to a single vendor.

Once a Month, I would like to generate one PO that brings all my inventory by regular Vendor up to its maximum stock level. This could mean 1 of X and 599 of Y.
Any suggestions to achieve this through MRP or other?

I do not recommend running MRP only once a month for all materials - but I understand that for non-critical materials which have short lead times, it is not worth reviewing all of them daily or weekly.

I would use lot size HB, MRP type can vary depending on your needs. Since you only want to do this once a month, I'm assuming you do not use material reservations, so I would use MRP Type VB Lot size HB.

I would create a contract and a source list for the material. Select the info record you want to use as a fixed source in the source list. (I know ... technically you do not need a source list. As long as you only have one contract assigned and no quota arrangements, the contract will be the default source of supply ... but in my experience it is easier for folks in the business to understand source determination if you use source lists. Otherwise, they get quite confused about why a certain vendor is getting automatically proposed by SAP, and you'll get a lot of questions)

Decide whether you want to use planned orders (if you're in ECC6.0) or directly create requisitions and set up your MRP job that way. You could set it up to only run once per month.

I would suggest you to use a single MRP Controller to group all of these materials so that your analysis for requisitions or planned orders is easier.

This is what I use on the Plant Maintenance side, not on the PP side - but simple MRP should work the same way for both.
