BW connection for BEx Query in Xcelsius is using cache

Hi experts,

I'm facing a problem, My dashboard isn't updating the data, we connected the Dashboard to a BEx query through the SAP NetWeaver BW Connection and It brings the data correctly the first time, but if during the execution of the Dashboard, the data suffer changes and you press the Refresh connection button, It still maintain the same data, It looks like It's using the cache and It isn't updating with the new data.

There is a way to configure this?

We are working with a SAP BW 7.31 SP 9 and SAP BusinessObjects Dashboard 4.1 SP 4 Version 14.1.4.1327 as development tool.

Thanks!!

Regards
