Regression tests? Make easy cube content downloads

It's been a while (aka long time) since I've last posted an entry to this blog. My apologies...

Ever wondered how to make life easier when executing regression tests on cube content?
Wouldn't it be easy to just download the cube content to excel twice and compare the 2 downloads?
To achieve the above, just use transaction RSCRM_BAPI



Via RSCRM_BAPI you can easily make query extracts and save these extracts to excel.
The preferred regression test way of working:
1) Execute RSCRM_BAPI on a query on a particular cube and download query result to excel
2) Apply changes to the transformation/update rule of that particular cube
3) Reload a subset of data to that particular cube
4) Execute step 1 (with the same variables)
5) Compare the 2 (created in step 1 and step 4) excel downloads and you're done!

That's all folks....
