I am doing levelling, in P6. whenever I am delaying any activity in "Resource usage spreadsheet" by shifting the particular overallocated resource to next possible day my original duration for activity changes drastically. This duration is logically never possible. If I show this schedule to management it is definitely going to be a butthurt.
Is there any possible way that I delay the activity and its duration wont change.
I can put lags but, some people recommend that using lags are not standard practice.
Please help.
