Product custom search logic in Web UI

Hi All,

I am facing a problem in implementing custom serach logic for products.

I have defined a new set type and assigned that settype to the product. Now the requirement is we need to have a search based on that set type, basically thats the old material number that is maintained is ECC.

I have identified the search object as

ProdAdvSearchRgProducts and the class is CL_CRM_PRIL_ADVSEARCH_PROD. Now what i want to do is to implement my own search logic in a Z class.

How do i do it? I have tried assigning the Z class in the view crmv_pril_obj in SM30 but its giving me error as "Set type guid does not exists".

Any helpful input would be rewarded.

Regards
