Defining Sub Tables via Filter Conditions
This is another great addition to the report container's feature set. Until LL25, related tables always needed to have an actual relation on the data source level in order to be usable as data source for sub items. If there was no relation, there was no way to insert the sub item, even if both tables in question had an ID field that would easily allow a custom linkage. In LL25, you can now have relations based on filter conditions.
