Pur Req from MRP RUN V/S directly created from Network

Dear PS Gurus,

What is difference between PR created from network(Pur indicator =PF) & PR created from MRP run.( Purchase indicator= WF-Reservation)

We still want 'Project Valuated stock' for Raw materials but customer wants PR created using MRP run(MD51) instead of directly from network . So we used Pur Indicator= "Reservation against" ... instead of PF which creates PR on Release of WBS. Once project is released MRP run creates PR as reservation already there.

PR are different( Suspect , it may have different behavior ) for example MRP created PR can be deleted & when in MD04 , don't have * while one created directly from netowrk has * against it  & cannot be deleted( Deletion bin is grey out) Also 'Closed' field is grey out as well.

I would expect this as process difference & should not generate objects with different attribute. Able to delete PR created from MRP seems like it is not tied to commitment or something missing.

All account assignment fields are populated in same way in both cases

Any insight to this?

Best Regards,

Jatin

Just to add more thoughts here:

MRP created PR and PR created through network does not have any difference in Fin. or cost accounting, but MRP generated PR is more flexible for use from logistics point of view.

I will always recommend it.

The main distinction is that you cannot group requirements and use lot sizing with NW gererated PRs.  MRP is much more flexible and powerful for combining requiremnts.

Hi Jatin,

PR created from Network activity cannot be deleted from ME52N or anyother transaction as system assumes this as a material required to carry out this activity / reserved for this NWA. So, if you have to delete, you have to get back to the network. In the case of MRP run, the PR is created when the MRP run takes place and here it is assumed that component required is not available in the stock and it is required to produce an SFG / FG. As this material is not going to get consumed directly against the NWA, it allows you to delete...

Thank you Balachandar for insight.  MRP run PR is used for exactly same purpose/Same Network & stock situation is same as well . We don't have FG/SFG in project & this material will be issued directly using CN25 to network. looks like there is no difference from cost & finance part , so that puts all q to rest.

Thanks you again
