Suppress Group Header based on Shared Variable

[nicmcd77]

I have a shared variable being passed from my subreport to main report (Lot Number). I am trying to then suppress the Group Header in the main report if there is no Lot Number but it's not working. I assume it's because it processes after the report? Is there any other option?

Formula in Group Header #1 of subreport:
WhilePrintingRecords;
Shared StringVar LOTNUMBER := {SQA_LOTS.LOT_NUMBER}

Formula in Group Footer #1 of Main Report
WhilePrintingRecords;
Shared StringVar LOTNUMBER;
LOTNUMBER;

Section Expert for Suppress in Group Header 1: if isnull({@Shared Lot Number})then true else false

You are aware that the shared variable will not be assigned until the next section in which the sub-report was called. So if want to have a GH suppressed. You may have a second GH (put your real GH there) and then put the sub-report in the first GH. But it appears that you have the sub-report in the GF, which should have a value for the next GF.
