Hi, We need to plan tasks over a period of 6 months. But when the next planning is done (months after the first planning) we need to know some details about the previous planning. For example, a person should not execute the same task twice in a row. So I need to know who did a specific task in the previous planning in order to verify that it is not the same in this planning. Do I need to persist the solution of the first planning? Is there any example amongst the list of available examples which can give me a head-start on this? Any help is greatly appreciated.
