Horizontal macros

Horizontal macros

Use a horizontal macro to generate a single complex expression that includes a set of incoming fields or a set of constants.
In a horizontal macro, a macro input field can represent a set of incoming fields or a set of constants.
In a horizontal macro, the expression represents calculations that you want to perform with the incoming fields or constants. The expression must include a horizontal expansion function.
A horizontal macro expression produces one result, so a transformation output field passes the results to the rest of the mapping. You configure the horizontal macro expression in the transformation output field.
The results of the expression pass to the downstream transformation with the default field rule. You do not need additional field rules to include the results of a horizontal macro in the mapping.
To write the results of a horizontal macro to the target, connect the transformation output field to a target field in the Target transformation.

Example

For example, a horizontal macro can check for null values in the fields represented by the %AllFields% macro input field. When a field is null, it returns 1. And then, the %OPR_SUM% horizontal expansion function returns the total number of null fields.
The following expression represents the calculations in the macro:
%OPR_SUM[ IIF(ISNULL(%AllFields%), 1, 0) ]%
At run time, the application expands the expression horizontally as follows to include the fields that %AllFields% represents:
IIF(ISNULL (AccountID, 1,0)+IIF(ISNULL(AccountName, 1, 0)+IIF(ISNULL(ContactName, 1, 0)+IIF(ISNULL(Phone, 1, 0)+IIF(ISNULL(Email, 1, 0)...
