Remove Group Header when Multiple Data Bands are blank

[katepassaro]

 Hello - 

I have a main report that includes a group header band, and then three sub-reports that are housed in three detail bands. I'd like to not print the group header if all three of the subreports are blank, but I can't figure out how to write a print when expression because it really is the data from three separate queries. 

Any ideas?

Just a quick update as I found a solution.

 

I created three smaller queries to combine the group header element, and a row count from each of the queries and then unioned/summed them. Using this as a where clause for my main report query helped only display headers that had sub query data.
