PDI transformation counter generated sequence

Use a transformation counter to generate the sequence

The following table contains options for generating a sequence from a PDI transformation counter:

Option	Description
Use counter to calculate sequence?	Select this check box if you want the sequence to be generated by PDI. This option is set by default Use DB to generate the sequence? is automatically selected if this check box is cleared.
Counter name (optional)	Specify the name of the counter if multiple steps in a transformation generate the same value name to avoid unique sequencing across multiple steps.
Start at value	Specify the value to start the sequence. For example, if Start at value is set to 1, then the sequence will start with 1. If Start at value is set to 0, then the sequence will start with 0.
Increment by	Specify the amount by which the sequence increases or decreases.
Maximum value	Specify the value to reach before returning the sequence to the Start at value setting.

For example, if you set **Start at value** to `1`, **Increment by** to `1`, and **Maximum value** to `3`, then the resulting sequence will be `1, 2, 3, 1, 2, 3, 1, 2`... If you set **Start at value** to `0`, **Increment by** to `-1`, and **Maximum value** to `-2`, then the resulting sequence will be `0, -1, -2, 0, -1, -2, 0`...
