Returns TRUE if the current member has the associated accounts tag.
Valid account tag defined in the current database. Any of these values may be used: First, Last, Average, Expense, and Twopass. To ensure that the tag is resolved as a string rather than a member name, enclose the tag in quotation marks.
The following example is based on the Sample Basic database. For members with the Expense accounts tag, the formula uses the @ABS function to calculate Budget as the absolute value of Budget.
IF (@ISACCTYPE("Expense")) Budget = @ABS(Budget); ENDIF;
