Exclude_below_line_depth is a single target data export variable.
It reports the depth of the exclude-below line for each single target exported.
This variable is exported only if an exclude-below line is specified on the Analysis page of the Variable Properties dialog box.
Note: This is an analysis variable that is available in a data export. Most analysis variables are only available in analysis exports and data exports are typically restricted to the data in a variable. This particular analysis variable is a convenient exception making it possible to calculate the depth of each target from the bottom easily from the one data export.
