How to restrict production order type wise work center

Dear experts,

I have a requirement, my client want to use production order type wise work center in production order.

Suppose while creating a production order if my order type is PP01 the Work Center should be WC0001.

I will maintain the Z table for order type wise work center. but on what logic system will check this as the order number gets generated after saving the production order. I want the error should occur before saving the order so that the user can change the work center accordingly.

Please help me to resolve this issue.

Thanks in advance

Mateen
