Condition exclusion for two conditions with same condition record.

Hi Experts ,

I have one requirement for exclusion of two condition types. This is required to avail export benefits. One of the Condition is FPS and Other is MFPS.

My requirement is,if material qualifies for both the condition types then system should fetch the condition records  of higher value .This i can achive by selecting best of two condition types but  where material qualifies for both the condition types and condition records are of same value i.e. suppose 2 % , in that case my requirement is to fetch FPS condtion type only. Please guide how i can achive this requirement.

Thanks
