I've a report with this group structure:
-> Question Block
-> Compare level
In the compare level there are two possible values: 1 and 2. My body section is hidden for
compare_level = 1. The values should be displayed in body section for
compare_level = 2 with
Previous() but I get zero. If I disable hiding on
compare_level = 1 I see the values correct. So why is
Previous() not working?
It seems that this error occurs only if I access a field of my datasource with
Previous(field). If I access a formula with
Previous(formula) which returns the field value it works.
