Category
Use this field to specify the category for the message for an internal system message generated by a Notify or Prompt action.
To use expressions to construct the category, click the button to the left of this field.
The contents of this field must use this syntax:
scalarExpr
where scalarExpr is a literal string or resolves to an expression that can be displayed as text.
When you click Event Actions form, the system "wraps" this content within a CATEGORY( ) parameter, which yields this final syntax:
to return to theCATEGORY( scalarExpr )
Note: If scalarExpr is a literal string value, the system automatically encloses it in
double quotation marks when returning it to the Event Actions form. If
scalarExpr is anything else, the system does not enclose
it in quotation marks.
