I have standard transaction groups for recipe management, and have created an additional ‘Historical’ transaction group that mirrors those tags to log any changes to those. When enabling, I get an ‘Unable to Start’ and can’t find anything in Gateway logs as to why. Any other troubleshooting, things to look for? All tag values look/seem valid, and it did create the table ‘automatically create table’ OK, just not logging changes of course. Thanks. ---

In your Transaction Group you have Status and Events Tab at the bottom, what do you see in the Events tab when you run into the ‘Unable to Start’ error? ---

Just this, ‘Unable to Start group’ and the ‘fatally\_errored’ not telling me much. However, in further testing, creating another group one at a time, so far I’m noticing something data type related? those Float4 are running fine, but when I add an Int4 that is mapped to a column in the SQL Server DB that is int is when I get the error? Still in midst of testing , perhaps more to follow. Thanks. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/d/3/d3f54b3128316fbd4f5dbfb392192c13ab30eb7d.png) ---

At this point with all the information you have regarding this issue, I think it’s best to contact Support for further troubleshooting. ---

I've also just encountered this issue. In my case it was just that I'd mistakenly set the Data source to default instead of the actual db I wanted to target. Worked perfectly once I switched it! ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/9/99b81157e76cb49043c1af48ed70ddecb96988e0.png)
