I am working on a report that gets, for example purpose, 5 columns from database.
Lets say ProductionCountry, Industry, ProductGroup, ProductId, Price.
I am grouping them on ProductionCountry, Industry and ProductGroup.
Visually its like this.

I have applied this expression to hide repetition of a group’s column data
=Previous(Fields!IndustryName.Value) = Fields!IndustryName.Value
But the problem with that is, this expression considers previous value from previous group.
If you can see the 2 red boxes in the image for Taiwan, I would like to show Hardware and LCD Panels in Industry and ProductGroup columns respectively. But the expression would hide it.
Any one knows how to fix it?
You need to check more than one criteria as you go down the hierarchy of values so you’ll need three Visibility-Hidden expressions:
For ProductionCountry:
For Industry:
For ProductGroup:
