If the Organizational Management component is integrated with Personnel Administration, note the following when using infotype 0001
Organizational Assignment:
You should interpret the staffing percentage entered in conjunction with the (planned) working hours for this position. In the Organizational Management part of the system, the (planned) working hours are stored in the position staffing schedule.

If you assign several positions, only the data for the position with the highest staffing percentage is taken into consideration.
