I have finished all of the trainings, and I did not know exactly where I should increment the TransactionNumber variable. This seems like something that should automatically happen within the ReFramework, but it does not appear so. It feels like it should be incremented after a successful completion of a process, but then any error would cause it to not increment, potentially creating an infinite loop.
I eventually landed on setting the initial value of TransactionNumber to zero and then incrementing as the first thing within Get Transaction Data. This seemed like the clearest, surest way that it would get done. How do you guys handle it?
