After updating & scheduling the program for weekly progress my manager asked me to show him the update, he particularly pointed out that the finish date of activity "Node 1 to 2 Bedding" (selected in screenshot) is not realistic as it take very less time (at the most 1 day for this area) and then he asked me to bring the date back to end of May 17 which as per current update shows finish in december 2017. My problem is that If i start doing this on program of 4600+ activities every week, i cannot finish my work ever on time. This is a Recovery schedule and i am permitted to change relationships & durations.
My question is that why does it happen and what are the ways to resolve it.
Regards
