Once the account tree elements have been selected in a new record and in the correct sequence order, it is not required to specify a sign but just the elements which are going to be included. The customized elements need to be elements located at the same level within the account tree, otherwise a "recursive" calculation may happen.
For instance the element "1900-Total Assets" is the sum up of three customized elements:
- current assets
- long-term assets
- and accumulated depreciation
as shown in the image below.
