HideInsideIV - XpressDox

You may have a situation where you have conditions that depend on the value of a data element during the lifetime of the interview.  For example, the condition on an OnExitSet command, or a ReadOnly with a condition.

This would be the case, for example, with a data source which was accessed “for all templates” and which retrieved information about the user (using the WindowsLogonUser value). Suppose you have users qualified by a category, being High, Medium or Low. And a Readonly command saying:

«ReadOnly(Name,IDNumber,(UserCategory = 'Low'))»

In all likelihood you would not want the user of the interview to see the value of UserCategory, and might be tempted to use «ExcludeFromIV(UserCategory)».

This is when you would use

«HideInsideIV(UserCategory)»
