| = Add value fields changing sequence |
| |
| == Description |
| |
| This transform simply adds a sequence value which resets each time a value changes in the list of specified fields. |
| |
| == Options |
| |
| Here are the options for the transform: |
| |
| * transform name : the name of the transform, needs to be unique in a pipeline |
| * Result field: the name of the output field, the sequence |
| * Start at value: the number to start at each time |
| * Increment by: the value to increase at each row in the same group |
| * Init sequence if value of following fields change: you can specify a list of fields here. If a value in one or more of these fields changes compared to the previous rows, the sequence will be reset to the start value. |
