How to Add Iteration Functoids to a Map
The Iteration functoid outputs the index of the current record in a looping structure, beginning at 1 for the first record, 2 for the second record, and so on.
For conceptual information about the Iteration functoid, see Iteration Functoid.
To add the Index functoid to a map and configure it
With the Visual Studio Toolbox active, click the Advanced Functoids tab to select that category of functoids.
The list of advanced functoids in the chosen category appears.
Drag the Index functoid (
) from the Toolbox to the appropriate location on a grid page.Note
The functoid will be placed on the displayed grid page. If you want to put the functoid onto a different grid page, you need to display that other grid page first.
Note
If you are constructing a map using more than one functoid together, you need to consider their relative left to right placement. Functoids are executed from left to right. The output of a functoid can only be input to another functoid that is farther to the right.
To establish the looping record input parameter for the Iteration functoid, create an input link by dragging a looping record from the source schema to the Iteration functoid, or by dragging the Iteration functoid to a looping record in the source schema.
To use the output parameter from the Iteration functoid, create an output link by dragging the Iteration functoid to a field in the destination schema, or by dragging a field in the destination schema to the Iteration functoid.
Note
The data type of the relevant field in the destination schema must be numeric or convertible to numeric so that it matches the output data type of the Iteration functoid.
