Maybe try to Edit LEVEL Properties -> Data->Filter String -> ADD (try here to add some kind of filtering like: " Is not null " or something - ()look at second screenshot)
I am not familiar with Pixel Perfect properties as there was never a proper help document created for i - so this is just a pure guess
Thanks Lech. It doesn't work for me. I have a working solution.
1. Select the report bound level you want to remove if there is no data
2. Set Visible to No
3. Press on the error
4. Click on the formatting Rules and create a new Rule.
5. Create your condition.
6. Set visible to Yes. You want to display the level when there is some data. This overrules the visible = no in the previous setting (step 2)
7. Link it tho the correct data member (same as in step 1.)
Click close and press on the arrow to apply your rule to the control.
