Dimension columns have this nice option to "Suppress when Value is Null", and expressions have this feature built-in. Unfortunately, for rows to be suppressed based on the outcome of expressions, ALL expression results have to be either 0 or NULL. As long as a single expression is producing reasonable values, the row will show.
Luckily, there is a trick available that lets you suppress multiple-expression rows based on the value of only one or a few of those expression columns. Since you can refer to another expression result by simply using the column label as if it were a field name, you can write something like this for any of the other four expressions:
IF ([Sub/Agg Brand Acc...] <> 0, ExpressionForOtherColumn)
Make sure that the label between square brackets is complete, as your screenshot doesn't show the entire label text.
