After doing some investigation, it seems like I could just add the InspectionID to the fact table.  There is a unique InspectionID for each board run through the inspection process.  This would then be a degenerate dimension.  How could I then create a measure in the fact table using this degenerate dimension such as [# of calls]/DISTINCTCOUNT[InspectionID].  I think that would give me the number of calls per inspection, but I'm just not sure how to set it up or if it can be done.

In the relational database, the Inspect_Result table holds a record for each board run with InspectionID as the PK.  This table  holds the pass/fail result.   If the board fails, then a 2nd table holds a record for each component that failed on the board.  So I have dimensions for Inspection Judgement (pass or fail) and also for component, so you can see how many failures you have for a paticular component.  There are other dimensions like machine the board ran on, program the board ran on, call type (reason the component failed), etc.    However, my problem seems to be that the Inspection Judgement is at a board level and the component dimension and call type are at the component level, but I need to have a measure of  "# of component failures / # of boards" .  Right now, I have a fact table at board level that has  the measure "# of boards" (1 for each record).  I also have a fact table with a record for each component failure.  So I somehow need to combine the two fact table measures to get "# of component failures / # of boards".
