Data Source compact display problem

Hi ,

There is a CrossTabs in my app ( I'm developing my application in SAP BusinessObjects Design Studio, ver. 1.6 ).

Also I have a datasource (BEx). I need to use "compact display" mode. See picture 1.

Pict.1.

Also there is  activated hierarchy.

My cross tab in run-time looks correct, but then a press on a leaf (red rectangle on Picture 2) it occurs an error.

"On select" event just simple row:

APPLICATION.alert("1") ;

Pict. 2.

Pict. 3. Error message after click:

Here is a text from log:

"(Error: N/A 99998)" and many many other rows, but there is no directly information.

Then I change back mode to full view (NOT compact view), then it works correctly.

See next image (full view of cross tab):

Picture 4.

So, my question is what should I do in cross tab settings or datasource to fix this problem?
