Difference in MRP between Planning with and without Final Assembly

[Former Member]

Hello Friends,

1) I want to get myself clear on this topic like, in the case of strategy 40, MRP RUN takes place for multilevel planning and makes planned order for FG, SFG and Raw. now how is it different with Strategy 10 ??

2) In case of Strategy 50 (Planning without Final Assembly), after making MRP RUN, what are the inputs will be shown in MD04 for FG ??

Regards and Many Thanks,

Rahul

Hello,

Planning with final assembly:

1. Stocks on hand reduces the PIR during MRP run.

e.g. if stock is 100 and PIR is 100, MRP run will not prompt 100 for procurement. if stock is 0 and PIR is 100, MRP run will prompt 100 for procurement.

2. Sales order creation reduces the PIR.

e.g. if PIR is 100, sales order 90, PIR becomes 10(withdrawal 90).

3. Delivery reduces the Sales Order.

Planned independent requirements are consumed by incoming sales orders so that the master plan is always adjusted to suit the current requirements situation.

Planning without final assembly:

1. Production quantities can be planned effectively.

2. Procurement of the components is planned by means of planned independent requirements entered at finished product level. The system creates special planned orders at finished product level for these planned independent requirements. These orders are only relevant for production once a sales order for the finished product exists.

3. The sales orders for this strategy are entered as individual customer requirements and are maintained in a separate segment in the planning run.

5. Final assembly is triggered once a sales order has been entered.

6. An availability check is performed on the basis of planned independent requirements.

7.The incoming sales order consumes the planned independent requirements.

Hopes it helps. please revert back.

Rahul,

I guess you must have overlooked the rules of engagement. It is customary in these forums for questioners to first perform basic research before posting any questions.

First, search in the forums (search box in the upper right of this page).

Next, search online help. This help is generic, and not generally specific to a particular industry:

For instance

http://help.sap.com/saphelp_erp60_sp/helpdata/en/cd/b8580b8e4611d1918c0000e8a5f6e6/frameset.htm

and

http://help.sap.com/saphelp_erp60_sp/helpdata/en/e0/71bb199c9f11d191920000e8a5f6e6/frameset.htm

Next search in one of the standard online search engines (such as Google).

If you have performed all of these tasks, and studied all of the online help that is supplied for free by SAP, then consider posting a question to these forums.

If you are unwilling or unable to perform such research, then you should probably engage a consultant to assist you.
