mrp development

Hi all,

I got a query here.

in my scenario reservation are arrived to ecc from CRM (service order)thru 'middle ware

while planning for reservation's.. normal mrp generates one PR which shows the accumulated qty of all reservations ,after calculating total requirement including safety stock,stock in transit.

what i need to do is converting PR to PO by manual or back ground.

then GI for PO.

But here the requirement is what ever the GI i do for PO should satisfy the PR individually and corresponding to service order(CRM).

How it can be done....whether i can go for Z development for ZPO

Here i got a plan like running standard MRP to create PR for all reservation into consideration.then converting PR to PO ...after that i have to go with devlopment like ZMRP...in which i will try to produce POa , POb,POc for one PO..then if we issue goods against POa,b,c..then respective service order can be satisfied....will this work...hw it can be done..

any one who has good knowledge in CS ..can provide help for me in this MRP issue

Thanks&regards

suresh

    Hi Suresh,

    Am not quite sure if i have understood your need clearly, but based on my understanding, you want to create one PR for each requirement, which in turn is to be converted to PO, so that you can trace which PO is meeting which order?

    If my understanding is correct, why don't you set the Lot size as EX in MRP - 1 view & in MRP - 4, set the indiv / coll indicator as 1 ?

    Check & revert.

    Regards,

    Vivek

      Hi Vivek,

      thanks,

      I think now u can understand my query better..

      Here i got service oder based on one qty.will be created in web ui.CRM.then that service order is linked to ECC by a middle ware.it uses internal order no.then reservation will be generated in ECC

      WEB UI CRM---- Middle ware --


      SAP ECC

      Service oder -


      Internal order no.-----Reservation No.

      Qty=1----


      Qty=1

      Like wise so many reservation will be created for a material in a day.

      I have one safety stock level in that particular plant

      I have intransit stock qty for that plant.

      Then system got to plan for net requirement calculation in ECC6.

      issue/recept will be done against PO.from supllying plant.

      so how it can be mapped ..

      Thanks&regard

    Suresh,

    In a MTS environment with Safety stock, you cannot have a one-to-one relationship between the sales order and the supplying purchase orders. The concept is illogical.

    As mentioned previously by Vivek, you can configure such that each sales order that is not going to be supplied by stock can have a single PR to support it (which you can automatically, if you choose, convert to a PO).

    No matter how you configure, though, you are going to have cases where MRP creates PRs that will in part or in whole be needed to create safety stock. These purchase reqs, and the resulting purchase orders, and the resulting GIs, will have no corresponding sales order. When a new sales order is created, and your ATP check decides to eventually make use of some of that stock, it will be difficult or impossible to determine how to map a PO to that sales order.

    If all you want to do is 'not aggregate the PRs', Vivek has given you instructions already.

    Regards,
