can MRP only create planned orders for ROH, not for FERT?

[Former Member]

HI all,

Is there any way to only generate planned orders for raw materials after MRP, forbid creating planned orders for FERT?

We want create planned orders for FERTs manually.

Thanks,

Harvey

Harvey,

If you want the FERT out of normal MRP run you could follow option as explained below

1. Change MRP type on all FERT to MPS instaed of MRP (Use type M0 to M1 instaed of PD)

2. So when Plant MRP runs it will not run for the FERT materials

3. You can then schedule MPS run separately for the FERt materials

If you have more questions please come back

thanks,

Harvey,

Try setting your FERTs to X0 MRP type (externally planned). This allows the manual creation of FG planned orders, but demand will still be exploded to components.

I explain in detail,

The current scenario is:

1. MD61 create PIR for FERT

2. run MRP, generate planned order for FERT, also for the child raw materials

We will keep step 1, but in step 2, we want only planned orders for child raw materials after MRP, no planned order for FERT in system.

That's the requirement.

Harvey,

Yes, that was also my understanding of your scenario. Did you try X0 for Fert? Run MRP against the entire plant, and MRP will not create any new planned orders for the X0 parts. It will explode the BOM and create dependent requirements in the components. In addition, you can create FERT planned orders manually, or using an external planning system, and these manually created orders will also create dependent demand on your components.

If you are also using Sales orders to consume your PIR, you will also have to look at requirements determination for Sales orders. This is configured based on MRP type. If you change existing MRP types, you may have to add SD config so as to continue to pass requirements to MRP. Your SD resource should be able to help you through this, or I can give you basic instructions if you decide that the PIR/demand/planned order/dependent requirements works to your satisfaction.

Many thanks, DB49.

I have tried X0 for FERT, but after MRP in the entire plant, I can't see any dependent requirements for the ROH, therefore there's no any planned orders for ROH.

The problem is if forbid creating planned orders for the FERT, how to pass the demand for the child raw materials?

We don't consider sales orders consuming the PIRs.

I think it is impossible to do so, unfortunately. Since dependent requirement is something attached to planned order of higher assembly. So FG planned order must exist to create dep.req.

Can I ask why you want to block planned order creation for FG? Maybe we can find the work around solution for you.

The production planners feel troublesome to change the MRP planned orders of FERTs, they think it is more convenient to create planned orders for FERTs directly, they don't want to see the system planned orders in MD16.

They just want MRP to give the procurement propsals for the raw materials after MRP run based on the PIRs.

So there comes the requiement.

[Former Member]

In your situations, I would suggest you set up the material master to P4, or M4 with planning time fence. In planning time fence system won't create any new planned order. Planners have to do it manually.

Since procurement proposal is also generated based on planned order, you need your planner to do this step first before run MRP.

For the planning period outside planning time fence you can ignore the planned order for FERT, although it is created, and focus on ROH only.

Good luck.

Hi,

One way to exclude the FERT materials from MRP is set the material masster in such a way that MRP type as " ND" no planning in MRP view.

if set ND for FERT, then how to generate planned order for the child component? we run MRP in plant level in background job.

[Former Member]

Dear Harvey,

At Plant level or material level ??

At material level run in MD03

At plant level.

we use MDBT run MRP
