MRP Control Parameters

Hi everyone,

We are in a blueprint phase right now and I just want to verify something. In MD01 or MD02 (Run MRP), theres a parameter there "Create Pur Req". There are 3 options:

Purchase Requisition - creates Pur Req for the entire horizon

Purchase Requisition in opening period - Pur Req for the Lead Time then Planned Orders onwards

Planned Orders - all Planned Orders

Is my understanding correct? Which field do you maintain the opening period? is it the planning time fence of the material?

Many thanks in advance!

Also, is there any way that you can run MRP and produce Prod Orders already instead of Planned Orders?

Thanks!
