Hello
Don’t know if this is a bug or a deliberate choice, but when you want to add a transformation on a field in a table that was opened in ‘new window (CTRL+W shortcut), then the section for Field Transformation is not available.
I have included a picture.
When your table is in the DSA/MDW node and you do right-mouse click, then you can choose Field Transformation.
When your table is in a separate window, then this particular option is missing
