Dynamics GP just does not offer a great way to apply credit memos or payments on a mass scale. If you typically apply credits to the oldest transactions outstanding, as most people do, this report could save you a ton of time. This report gives you all the details needed to filter down which vendors and credits you want to apply, then it creates a GP Macro for you with that data only. From there, you save the macro file and run it in GP to save you TONS of time.
This type of report can go so much further, outside of just auto applying transactions. Get creative with it, and lets automate your environment together!
