Drill through action with two fact tables

Hello,

I have a situation where two fact tables (views) are used in cube. There is a dimension field which is present in one fact table only.

Now when I want to use the drill through with that dimension field, I am getting error

The selected action cannot be completed because of the following error.
Errors from SQL query modile: The attribute "X" in the dimension "XD" is outside the granularity of the measure group "M1" and cannot be returned as a column.
This error may have occurred because the definition for the action is not valid. Verify the definition using Actions view

Please help

Thanks in advance.
