Is it possible to amend only one article in the schedule without prejudice to the other articles?
هل يمكن تعديل مادة واحدة فقط في الجدول دون المساس بالمواد الاخرى
Est-il possible de modifier un seul article de l'annexe sans préjudice des autres articles ?
What did you mean by "modify"? Change day/time only? Or change subject/teacher/student of an (sub)-activity?
You should load the generated FET file from the results folder.
Each activity got a preffered time constraint in that file.
Just modify that constraint and generate again. (That will take just a second and give you the same result)
When adding a professor in a subject and redistributing the cohorts to the professors, is it possible to keep the schedule fixed and change the schedules of the professors of that subject only without affecting the other subjects?

Lors de l'ajout d'un professeur dans une matière et de la redistribution des cohortes aux professeurs, est-il possible de garder l'horaire fixe et de modifier les horaires des professeurs de cette matière uniquement sans affecter les autres matières ?
عند اضافة استاذ في مادة ما وتعيدي توزيع الافواج على الاساتذة هل يمكن ان يبقى الجدول ثابت وتغير جداول اساتذة تلك المادة فقط دون المساس بالمواد الاخرى
That is depending on your dataset. If it is easy, then it is possible. But with difficult timetables you will get conflicts by that.
If you want to do it, then you need to do it similar as i wrote above:

If you got conflicts, you need to modify your constraints. Or unlock (some) activities.
