Mark,
The "Tests" and "Parts" tables are currently related with a 1 Part < many Tests relationship. However, I don't want to display the average Test "Efficiency" of the Tests currently related to this Part.
Instead, I want to display the average Test "Efficiency" of ALL Test records of Type "A" (for example) where the Test "Date Created" matches the Part's "Ref Date" field or is within the same week as the Part's "Ref Date."
So each "Part" record potentially has a different "Ref Date," and this would result in a different set of the full list of "Test" records to be averaged.
Does this make sense?
Thanks!
