How
A column with a "Position:" of '0' will not be included in the output of a report.
Purpose
Why have a column on a report that is hidden?
- The value of a column can be used in another column using the column variable 'C??'.
- If you are using a variable that is time consuming to evaluate (e.g. Period totals) and you use it more than once on a line, having it stored in a hidden column and accessing that column would mean that time consuming variable would only be evaluated once.
