Cutover for PIR & MRP Live

[Former Member]

Hello Friends,

The business scenario is as below-(It's a food company)

There are 2 ECC systems, A & B. The MPS run is taken in system A and netted off requirements are being sent to system B via IDOC so that PIR's can be created in system B and then a subsequent MRP run in system B.

System B performs MRP run, but only for Packaging and some ingredients so that these things come into Plant B on time. Now they want to use full fledge MRP for manufacturing also although they have Process orders running on 1 of their plants.

What would be the cutover strategy in this scenario?

Pl provide your responses.

Thanks in advance,

Rohit Nanday

Dear,

I hope you would like to have full fledged MRP in system B where you will have netted demand in term of PIR from system A which is result of MPS. From cut over point of view there should not be any open process or purchase orders. Clear all PIR too. Take fresh MPS run and then run MRP over it.

Hi Rohit,

              As Brahmankar said, there should not be any OPEN purchase orders/Process Orders/Schedule lines (if used). Adding to the above,First Run MPS and MRP. It is strictly instructed that MRP should be run after completion of MPS. Then convert the planned orders to Process orders.

Hi Rupesh,

Clearing PIR's mean should the old PIR's be deleted as on the go live date?

Thanks.

Hi Rohit,

Yes clearing PIR means delete all existing PIR.  Close/complete or delete all the existing MRP output(PR, Planned order,Process order etc)

At the time of going live upload PIR. Dont foreget to use processing key "NEUPL" for the first MRP run.

Dear,

If you have unconsumed old PIR - before go-live date PIR you need to reorganise it through MD74.

Dear Rohit,

                      First time MRP to be run with NEUPL key  to inset all materials in the planning file. Remember, materials with "ND" will not be considered for MRP and will not have planning file entry. If you do not run with NEUPL(this will not happen)/Do not have entry in planning means, Manually you need to insert  via MD21.

Please close the thread if you get the answers.

Dear Rupesh,

What are the benefits of reorganizing unconsumed PIR's and closing the open process and purchase orders as well as schedule lines with respect to cutover?

Thank you.

Dear,

If you want to have correct MRP out put then there should not past dated or unconsumed forecast.

As you will have the order for it already in system. if yiu have unconsumed forcate system will planned it agian.

It is not necessary to closed all open PO and Orders

System B performs MRP run, but only for Packaging and some ingredients so that these things come into Plant B on time. Now they want to use full fledge MRP for manufacturing also although they have Process orders running on 1 of their plants.

So if you want to all materials in MRP better to close all the existing PO and Orders so that you will have fresh order and components planning through MRP without any mismatch and shortfall.

Hope clear to you.

Dear Rupesh,

I am not yet clear.

In one of my clients plants, they have the process orders running, so there are goods movements on them(GI,GR). Should these open process orders be closed before MRP run?

What about PO's and sales orders? Should they be closed before going live with MRP?

Also explain what should be cutover strategy w.r.t unconsumed PIR's?

Thanks.

Dear,

Please take a cut over at moth end where mostly we close all open orders.

so there are goods movements on them(GI,GR). Should these open process orders be closed before MRP run?

You will have new orders after MRP run just convert them in process order and do the further processing.

What about PO's and sales orders? Should they be closed before going live with MRP?

They should also close because these PO were created manually may be they will have less or 

higher quantity and after MRP run these PO will not changes as it is firmed receipts.  So if you want to have the exact quantity orders you need to close them and create new. Sales order point of view there is no issue.

Also explain what should be cutover strategy w.r.t unconsumed PIR's?

Please re-organised PIR to current date by MD74. So please do this on last day of month and take MRP run after that. So from 1st you will have new order for processing.

Dear Rupesh,

My client wants to go live on 17.05.2013(Friday).
