Hidden_Text
This is tied to the Invoice system.
Default Hidden_Text = 0
You can can suppress text entries that start with an '!' - it is a little clumbersome. If Hidden_text = XX (where XX is one of your analysis codes) - if the 1st character of the text box is an ! then all text will be added under that analysis code. This allows you to easily suppress work without having to remember to enter multiple !'s.
