ReFramework - Using Files in a Directory (Template)

Continuing the discussion from Process All Files in a Directory using RE Framework:

Hi All,
I would like to process all files in a specific folder based on the ReFramework. I have already tried to adapt the solution in the attached post. I would like to use the TransactionNumber as an index.

You can also find my project here. Can someone help me or even provide an appropriate template? Many thanks in advance! (983.5 KB)
