MRP Run for a specific period of time in future

[former_member830646]

Hi team,

We have a requirement of running MRP for a specific time in the future (no starting from today), but at the same time, if required, being able to run it for the whole period.

Example:

- MRP run daily for Material A starting after the "planning time fence" o frozen period of let´s say 30 days.

- MRP run once a week for Material A for the whole period.

We have evaluated the option of using MRP types P1/P2/P3/P4 with a specific planning time fence, but this it not completely useful, as you cannot run it later once a week for the whole period - unless you mass change all materials to PD before.

We have also evaluated Planning Horizon, but it is not useful as you cannot start the run from day +30 (for example).

Is there a way of achiving this requirement?

Any input or idea is very welcome 🙂

Thank you!

What is the specific business requirement that you try to achieve?

[former_member830646]

We want to be able to freeze the first month for all materials, so MRP cannot create Planned Orders or Purchase Req during this period... but, when they have finished to reschedule orders and they have planned the next period, they want to be able to run MRP for everything.

Hello eva.garcia.26

Honestly I don't understand how you are going to plan with this kind of process. You won't have any information on supply plan in the current month if MRP can't plan there. Then once MRP is released, all of a sudden you will get supply proposal from MRP in the current month. Also as MRP plans backwards, there might be to little time to procure all the components for the current month. I would challenge the process and rather go with standard MRP settings or with planning time fence i.e. P1-P4 MRP types if you need to freeze the plan.

If you still want to implement this way of planning consider using manual firming date in MD04, menu option: Edit -> Set Firming Date. This way MRP won't change supply plan before the firming date. The date needs to be set up manually in MD04 by the responsible MRP controller.

You could automate that with the MD_SET_MFXDT function. Firming dates are stored in the MDFD table.
