Issue on Number Range for MRP Purchase Requisition

Hi Gurus,

Please help me on the issue explained below.

We are already using SAP ECC 6.0 and SRM 5.0 and now we are implementing Plant Maintenance Module.As a result of this implementation ,we have created number of PR document types and assigned to unique number ranges in ECC. One of these document types has been maintained for MRP group for a material type in order to identify the MRP purchase requisitions created on the shortage of the materials for these material types.

This functionality is working fine. MRP run for the materials is picking the appropriate PR document but number range of the document is not the same what was assigned to the linked document type.Some other number series is getting picked by system .

There is setting under SPRO Consumption Based PlanningNumber RangesPurchase Requisitions

Here, number range assignment is against plant. This is the same number range which is being taken by system on running MRP. But the desired number range is the one which has been linked to PR document type.

If I change the number range above then number range for MRP PR in present system will get affected..

Can you please advise me on above so that PR generated on MRP run should have appropriate number range?

Thanks & Regards,

    As per my understanding, what you have mentioned above is exactly the way SAP is designed. Its SAP Standard behaviour.

    But if you check your PR document type - no:range & the CBP no:range both will be same only since both refers to the same object.

    Please check the PR document type that you have assigned in the CBP & its no:ranges.

    Thanks & Regards,

      Hi Ram,

      Thanks for your reply!!!

      Number range for PR linked in CBP has different number range from the one assigned to this document type.I want SAP to pick the number range assigned to the PR document type not the one in CBP.
