Hiding a filtered table until a row is selected in the main table

[Anonymous]

Help.

I have 2 tables (visuals) in my canvas, both built out of a dataset connected to my model via direct query. Call them table A and B, where A is the main table.

Now, selecting a row in A filters the content in B (ie, B will only show the fields for the item selected in A).

Clearly, when I launch the report, no row is selected in A (and, afaik, there's no way to preselect a table row in BI), meaning that table B greets you with a bunch of content that may be confusing/misleading until it's filtered by a row selection in A.

What I want to do is write a measure that will hide the contents of B until a row is selected in A. 

I've tried the usual stuff like IF ( NOT ( ISFILTERED (tableA[xxx])) , BLANK())) but it doesn't work.

Any hints appreciated. Thanks.

@Anonymous ,

What is the common key between these two tables?

Can you try the below approach if your requirement matches with that one?
