Hello @Marcel.Ausan
Thanks for your feedback, but I don’t understand the screen you are showing, it’s probably because we are still using the UPD5 of IFS ….
On my side, I had a look at IFS packages, and I found Fnd_Session_API.Get_Language to get the user language. I made some tests in which I was in french and in english versions, in both cases, I could get the right language ISO code.
EDIT : I think you are not showing a possible response to my question, it’s not a matter related to the prompt of the custom fields, but it’s about the script behind my read only custom field which returns a text which needs to be translated
