Save target as is only possible from the Editor view with the file opened there. From the view you show here you have to use the batch task "Finalize", which will update your TM and create the target file. This is the recommended way of working, as this step makes sure your TM will contain the most recent version of your translation.

Thank you Jerzy Czopik , your reply is really useful but I have just tried to use the batch task but when I right click on it (or even if I click on "BATCH TASK" on the ribbon) it is written "No task available" (in Italian, "Nessuna attività disponibile"). I attach a picture...What am I doing wrong now? Thanks!!!

Go to Projects View and check, if the project is not marked as completed. Or is your target language other than French? In that case simply change the language side in the Navigation pane on the left.

Jerzy Czopik the target language is french, right! I have to translate from Italian to French.

The project is "completed"

With a completed project you have no batch tasks. You have finished the project, so TS correctly assumes there is nothing more to do there. Revert the project to "In progress" (right click on it) and you'll be able to work on it again. This includes batch tasks.

Why don't you just open the file for translation? It doesn't matter whether your project is complete or not. Double click the file (or right-click it and select Open For Translation) and use the Save Target As command as you usually do. You don't need to finalize anything or revert it to In Progress.
