Empty XCELSIUS dashboard after BW upgrade

Hello,

we have an XCELSIUS dashboard with lot of BW connection.

This worked correctly on SAP portal until BW upgrade 7.01 to 7.4.

After this upgrade, the dasboard has no data on new portal, just the charts.

I think It's happened because of ABAP/JAVA stack split...

Whan can I do? The users need this query WITH data.

Thanks,

Balazs
