For background, a couple of tables were set up for generating data to target. When attempting to use Datamaker, the application crashes as soon as it starts writing the data to target without giving any error.
There was space in the Target connection name which was crashing Datamaker. After reviewing the name and correcting, the issue is fixed.
The take away is to always double check your connection values. Spaces have proven troublesome in the past on many occasions. The next is simple mis-spellings.
