SAP ERP Manufacturing - ProductionPlanning (SAP PP): Indicator 'CreatePurchase Requisitions' is not considered byMRP

Posted by Caetano Almeida 29-Sep-2014You are running MRP for a material and you have defined a value for for the field "Create purchase requisition"on your variant. However, the value defined on the variant is not considered when you run MRP in backgroundor in transaction MD01.

For example, you have defined the value "1 - Purchase requisitions" on your variant and you expect to havepurchase requisitions created by MRP. However, after the MRP run, you observe that only planned ordersare created. When you try to plan your material using MD02 or MD03, system correctly creates the correctreplenishment proposals, according to the value defined for this parameter.

Why this is happening?

Besides the parameter defined on the MRP variant, it's possible to define a different value for the MRP Group.Therefore, if this is happening on your system, you should check the following points:

1 - Check if there is an MRP group assigned to your material on tab MRP1 of the material master (tab MRP2).

2 - On the customizing transaction OPPR, click the button "Creation indicator"

3 - Here, check if there is a value defined for the field "Create purchase requisitions"

There are some important remarks related to this issue:

1 - Even if there is no MRP Group assigned on the material master, when there is an MRP group with the keyequal to the material type key, this MRP group is considered by MRP. For example, if you have created theMRP group FERT, it will be considered for all the FERT materials where an MRP group has not been defined.This system behavior is defined on the following note:

34013 - MD04, MD05: Material type as MRP group

2 - The values defined on the creation indicator customizing are not considered when running single-level MRPon transactions like MD02, MD03, MD41, MD42, etc. You can find more information about the system behavioron the following note:

23922 - MRP: Creation indicators, PReq. or planned order

3 - The same logic is valid for the indicator "Schedule lines". However, it is also possible to define a value forthe creation of schedule lines at plant level on the customizing transaction OPPQ. You can find on the section"external procurement"

AKS Sankar29-Sep-2014 06:44Hi Caetano Almeida,

It's really a trick information, it's too hard to find the root cause without understanding this logic.I checked in'Parameters for DS' but,I couldn't find the option to control the 'Delivery schedules' parameter in OPPQ. Couldyou please point out, where we need to assign this value in OPPQ to control 'schedule line' in MRP?

Thanks
