Description

This transform simply waits until all the transform copies that are specified in the dialog have finished.

You can use it to avoid the natural concurrency (parallelism) that exists between pipeline transform copies.

Option	Description
Transform name	The name of the transform to wait for.
CopyNr	The (0-based) copy number of the transform. If the named transform has an explicit setting for "Change number of copies to start", and you want to wait for all copies to finish, you’ll need to enter one row in the grid for each copy, and use this column to specify which copy of the transform to wait for. For the default number of copies (1), the CopyNr is always 0.
