I am using an Append Only Comment field in my SharePoint list, which I am updating via a Microsoft Automate workflow. I do this several times in a single Flow, and it works great at the start of the Flow.

The problem I have is: when I finally use a "Check In file" action at the end of my flow, the last comment is duplicated. Is there a way I can avoid this duplication?

Much appreciated.

  • how did you design your flow? To understand this issue better, please provide some screenshots about your flow actions.

I was able to resolve this by using an Update Item action that simply sets the Append-Only Comment field to null.
