Hi All ,

I have done the necessary configurations in PP say

Order Type

Order Type Dependent Parameters

Scheduling parameters for planned & production order

Confirmation parameters

Availabilty check etc

and iam able to create planned & production order and confirma the production order.

I want to configure for MRP: -

Settings done are

Have activeted planning file entry for all plants.

When i run MRP system throws a error <b>Number range for object MDTB does not exist - Message no.61501 </b>

Is there anything to do with plant parameters OPPQ and Mrp Group OPPR.

I just tried plant parameters,standard 0001 is not available for copying.

Suggest me how to proceed to set MRP.
