@ISATTRIBUTE

Returns TRUE if the current member under calculation matches the attribute or varying attribute name specified in attmbrName.

Syntax

@ISATTRIBUTE (attMbrName)

Parameter	Description
attMbrName	Single attribute member name or member combination.

Notes

This function provides the same functionality as @IsMbr (@Attribute(attMbrName)), but is faster.
You may have duplicate Boolean, date, and numeric attribute member names in your outline. For example, 12 can be the attribute value for the size (in ounces) of a product as well as the value for the number of packing units for a product. To distinguish duplicate member names, specify the full attribute member name (for example, @ISATTRIBUTE(Ounces_12)).

Example

Consider the following calculation script, based on the Sample Basic database:

/* To increase the marketing budget for markets with large populations */
Marketing ( 
  IF (@ISATTRIBUTE(Large)) 
    Marketing = Marketing * 1.1; 
  ENDIF 
);
