I have pulling my hairs out in the last couple of day, could not understand why this happened, can someone please help? This is an issue with the Summer working only activities (which have been assigned to the Calendar with restricted working in summer months only June, July, August and non-work in all other months).
Fixed duration is 65 days and I have been working on this programme for the last few year with no problem. It has always shown those activities from 28 June to 31 Aug (same year) in the baseline, FF relation ship with the construction activity (as predecessor) which finished in November same year. However, in the current forecast, with nothing changed to the duration or logic or calendar, the start date is 28 June but end date is now 1 June the next year (the predeccessor activivities stayed the same, i.e. still complete in Nov same year). I have tried every test I could, such as decrease duration, extend working period on the calendar etc, but it did not work.
Hopefully someone knows what is the issue here? Many thanks
