Hello, I am new to FME desktop, I make a workspace to compare data between agol feature line attributes and an excel file on my device, then I tried to update the changes on agol feature.

The error message states that there's one or more features without a coordinate system being written and the AGOL writer does not like that.

If you know what coordinate system your data is in you can use a CoordinateSystemSetter to specify that.

You are right, i placed a coordinate system to the excel file and it works perfectly, although its a little strange to assign a coordinate system for table, however, it works 😃

thanks alot
