[QAAWS on SAP BW query] - data update process in XCelsius is too long

I have XCelsius dashboard which uses QAAWS connection: XCelsius >> QAAWS >> BEx query >> SAP BW InfoCube

When I load data into InfoCube - XCelsius dashboard updates data after 20 minutes or more

QAAWS settings are following:

- Refresh on load

- Refresh every 60 sec

I suppose that XCelsius cashes data...

How to improve update time so I can load data into BW InfoCube and see the updated data on the XCelsius dashboard without waiting for 20 minutes?
