Not retrieving data when there are too much BASMEMBERS

Hi, i'm having trouble with an interface in BPC 10,

the model has 13 dimensions, and when more than 7 dimensions are expanded as BASMEMBERS the report becomes empty.

So, it works if i use a single member as expansion of a dimension, but when i expand any other dimension as BASMEMBERS, the report can't retrieve data. I don't know if it is because the tuples are to much to calcute (even if i use the "suppress" in the report), or something else. there is some kind of limitation i'm not aware of?

I'm currently using BPC 10, SP 20

Thanks in advance
