Keyword warn List Attribute

Purpose
The warn attribute adds a logical expression to the property. The condition described by the logical expression is checked after the scheduling and a warning is generated if the condition evaluates to true. This attribute is primarily intended for testing purposes.
Syntax warn (<operand> [(| | & | > | < | = | >= | <= | !=) <operand>...] | @ (all | none))
Arguments operand

An operand can consist of a date, a text string, a function, a property attribute or a numerical value. It can also be the name of a declared flag. Use the scenario_id.attribute notation to use an attribute of the currently evaluated property. The scenario ID always has to be specified, also for non-scenario specific attributes. This is necessary to distinguish them from flags. See columnid for a list of available attributes. The use of list attributes is not recommended. User defined attributes are available as well.

An operand can be a negated operand by prefixing a ~ character or it can be another logical expression enclosed in braces.
