Hi @Ayres, Matthew ,
Regarding the automatic filling of list data, there are other ways besides Power Automate.
- Use the calculated column
I observe that your data is regular, and it increases according to the date column next to it. Then you can set Ticket as a calculated column, which can also be automatically filled. You can refer to this article:
However, this method is not very stable. I tried it in my environment without success. Give it a try if you want.
- Using Power Apps
Power Apps is a great tool for customizing forms. I found a post that seems to be very similar to your needs, you can refer to it.
If you think it meets your needs, because the current Q&A forum does not support Power Apps, I suggest that if you have any related confusion, you can go to the Power Apps Community to create a new discussion to get more professional help.
Finally, of course, you can also use Power Automate. Flow is also very powerful. If you want to know the relevant details, you can go to the Power Automate Community to issue a discussion in order to get more targeted help.
Hope to help you.
