Preformula
In most cases, you will define the input objects of a table using the parameter field. However, you can also use a preformula. This is a formula that is evaluated before the column formulas of the table and with which you can filter or edit the input elements of the table (e.g. sort by gains/losses).
The input object of a table in Infront Portfolio Manager is always a value list, e.g. a folder. This has the advantage that table entries can also be created for an empty list (based only on the table parameters). In this case, the table also has an input element, namely the empty list itself.
