1. I am looking for a solution on how to assign persons to positions on the organizational structure. i have created a structure with validity period from 01.01.1900-31.12.9999 and have also created corresponding positions with the same validity periods but am failing to assign persons in this structure. the system says, "the object cannot be assigned to the position object because it does not fall within the relationship period 01.01.1900-31.12.9999"
