How to link "Priority" in RRP3 with PP order types

Hi Gurus ,

I have a problem with "Priorities" defined in RRP3.On pressing F1I can see as below:-

4: Cutting/Rewinding [NCRN]

5: Repair [NCRN]

6: Rework [NCRN]

7: Strip [NCRN]

Above are the processes in Production under one order type NCRN with one number range ,but different Business process.

Order type NCRN is configured in ECC as per business.

Now we need to have different order type with different number range for different processes in place of NCRN order type.

I have created 4 different order types with different number range in ECC and did necessary config .

But when I am try to convert by changing Priority in RRP3, it is still taking same number range?

Can any body guide me on this,plz or anylink in config is missing?

Awaiting feedback

Best Regards,

NN
