This activity is used to update the Work Task planned dates and resource allocations outside scheduling engine. This can be done in Work Scheduler Gantt page or in some of the other Work Task pages.
When updating the planning information of Work Tasks outside Work Planning and Scheduling solution, it is important to note that these updates can get overridden if the Work Planning and Scheduling process is running in the background for the same Site. To avoid any overrides, the date change must be made to change the Work Task Fixed Start date also. In addition, any manual resource assignment should be done in the Resource Demand for the work task as well, in addition to the Resource Allocation.
