Quota grouping

I need some help with quota grouping for employee groups and sub groups. Based on the combination of PSA and EG& ESG, applicable quotas vary. I'm confused on how to do Employee sub group grouping. Can some body tell me as how complex it will be if do one to one grouping for PSA and ESG grouping. We have 9 Personnel Sub areas and 40 Employee group and sub group combinations.

Thanks,

Rajiv
