MRP resulting in multiple requisitions for same material

Hi,

I´m having some difficulties with MRP for my client.

I have set up lot size as MB for monthly.

I am expecting one requisition for one material, however when it runs it creates three.

Can someone explain to me where that is controlled and with what criterias?

I am also after knowing how to group multiple requisitions for same material into one line on the PO.

When running the ME59N it creates one line per requisition, however im sure it should be possible to group into one line on the PO?

Really appreciate any help.

    • Environment is in the menu after you display the requirements data. Those settings are not required. I mentioned them so that you don't have to go to different transactions to see different data.

      Like the above poster mentioned I would suggest you to run MRP using MD02 with settings like following.

      Processing key: NETCH

      Create Purchase req. : 1

      Delivery Schedules : 3

      Create MRP list : 1

      Planning mode: 3

      Scheduling: 1

    Hi Jimmy,

    For the first question (More than one Preqs as a result of MRP):

    More than ane Preqs are possible as a result of MRP run becuase of different delivery dates, so based on your planning parameters you must have different requirement date for that material and so you are getting multiple Preqs.

    For second question (Clubbing Multiple Preqs in a single PO):

    You can use ME21N and select one of your Preq (using Document Overview option), this will create one line. Now to accomodate other Preqs in this single line, put all others Preqs in delivery schedule tab of the PO.

    Thanks,

    Yogesh

    dear friend,

    those 3 reqs mean that your stock is not enough yet...

    first of all, i would recommend to re-run MRP (you would use MD02 for this particular material)

    after that open MD05 and check out the current requirements.

    you will probably see the new situation.

    please take into account that master data plays significant role as well

    -do you have Safety stock (MRP 2 view)?

    -any coverage profile is set?

    -...

    good luck!
