Production version selection based on Process order type

Hi,

I have the following requirement.

A material is having two production version one is for R&D and one is for regular production. Now two process order types one for R&D and one for regular production. Now during creation of process order if we use order type of R&D then it has to select production version of R&D and if we use order type of regular productionthen it has to select production version of regular production. This selection has to be happened automatically. How this can be configured.

Thanks
