Composite Provider in BPC 11.0 FOR SAP BW/4HANA

Hi,

I have attached one ADSO, which created by myself to a BPC Composite Provider. I created a EPM Report in MS Excel. If i query the data from a parent node(Hierarchies in ACCOUNT), there is no data. But if i query from a child node, the data comes to appear. I don't know why that happened.

Best regards.
