Views in Ax 2009 EP problem

[paucer]

Has anybody bumped into such strange behaviour:
I try to create simple report for EP which consist information from joined InventSum and inventDim.
When I use view with these tables joined - no report is displayed in EP.
If i change the report with those tables joined in reports datasource - then it works fine.
Any clue why or what is wrong?
