I have many labels in en-us lets say 100 labels. Now I want to convert each of these labels in arabic. How can I do this at a time.??
I never still do that in my work, but I worked on labels import/export on DAX 2012.
You need to export your EN_US Labels in AOT on a AxYYYen_us.ald (Export File with a right click on your personal Label ressource (YYY)
Open it with notepad and translate all terms (keep all @YYYNum to provide translation)
Rename it on AxYYYar.ald and import it (with overwrite, so backup with an export just before the original Labels Languages).
Labels are managed on database directly in DAX 2012 AOT, but I had somes synchronization issues between ald files on server and AOT's labels : After import, I hadn't all labels availables.
So, to be sure, you could replace ald files on server (..MicrosoftDynamicsAX\bin\Application\Appl\Standard) and import your ald files in AOT by MorphX.
