Thanks, Zoltan. I checked the calendars and there laid the problem, holidays weren't assigned in default calendar of one computer.

1 check the calendar again if it is using the default calendar then default calendar on your computer and the compueter where it came from may be different.

2 Also check the calendar at the bottom where it says to Inherit holidays and exceptions from Global Calendar that the correct one is choosen.

3. make sure that the data date DATE and TIME are the same

4. in the calculations options make sure they are using the same way when calculating successor relationships
