Can't import vector file

After subsetting, the vector file isn’t imported into the image. What is the problem?

What’s the error? Which product do you use? Which vector file?

The “Import ESRI Shapefile” tool is disabled.

have you tried File > Import > Vector > Shapefile?
It is important that the product where the vector should be imported into is opened and selected in the Product Explorer.

Yes, the selection is sometimes a bit stupid in SNAP.
Please make sure that the product is highlighted in blue and then select the action again from the menu.
