Is the following box ticked in FME options "Inspect with Data Inspector when Visual Preview window is closed"

In Tools -> FME Options -> Workspace there's a setting to open the Data Inspector when the Visual Preview window is closed, that's the way to do it.

Inspection has been moved into the FME Workbench starting in 2019.0, combined with feature caching it gives you a lot more options for inspecting the flow of your workspace.

The Tools option is the solution, except when you run the workspace from a batch file.

For that missing option an Idea is posted here

Hi,

Thanks a lot, it has worked!
