Customer is using the standard form template for a custom Aggregation Rule. 123456789Test

When the Aggregation Rule is changed the customer must also change the form to display it properly. 

If you're using Posting_Period as an Aggregation Rule, you need to show the AggregationStartDate as table title. When you use other fields it's necessary to show the AggregationName. This means, when you change the Aggregation, i.e. create a custom aggregation, you'll need to adapt also the form to show the proper values because our delivered forms are all made for the standard rule. 123456789Test
