What is behind those numbers in a PPS 2010 Grid Report, and why can't I see my newly created drillthrough actions in SSAS 2008?

In order to cleanly validate the numbers behind the measures in a PPS report, I designed several new drillthrough actions in SSAS 2008. I use these actions so the user does not see the dimensional surrogate keys, and cleanly brings up the meaningful detail attributes and measures in a tabular format. The report has three filters, and selecting each measure brings up a separate drillthrough action via the "additional actions" by right-clicking in the measure cell.   Well, the only problem is, I could not access them from a previously created report.  I could view them in Excel and SSMS, but not in the PPS Report.  Ok, I am not a fan of providing a ton of detail in a PPS report since I consider it to be a "Performance Tool" with high-level aggregated values. Not to mention excel should be the first choice, as most likely the user is just going to save the detail anyway in Excel for tabular analysis.

At any rate, the only fix was to recreate the report, even after saving (publish in 2007) the datasource, report, and filter again.  What a major bummer!

Hopefully the RTM build will have the fix ....soft in the middle.
