So, I have created the similar project from the beginning once more. This time I made one change in the file structure, since during recording of AS02 I noticed that filed "Cost center" appears two times (after change of Cost center I need to confirm the change "Do you want to overwrite the existing time-dependent data?" and then go to next tab). In my previous project I deleted this line, now decided to leave and adjust uploading file structure accordingly.
Unfortunately during SM35 run I still need to confirm changes for each master data by pressing Save button
