After 3 months of hard working, we finish a schedule with 5 Day Workweek calendar like picture:
Then the Construction team said that “06-Mar-18 is the right Project finish date, but we’re talking about 7 Day Workweek, not 5 Day Workweek. Sorry pal, it must be a misunderstanding.”
What the he**?
Changing Activity calendar will change everything.
Normally, if we change calendar to 7 Day Workweek, all activity finish date will change like below picture:
Now Project finish date is 25-Jan-18.
I will show you How to Change 5 Day Workweek to 7 Day Workweek but keep Project Finish Date unchanged.
Step 1 : Go to menu Enterprise -> User Defined Fields
Create a field called “Finish 5DW” with Data Type : Finish Date. And “Start 5DW” with Data Type : Start Date
Step 2 : Go to menu Tool -> Global Change.
Create a Change “SaveTo5DW” with detail like below picture:
Click “Change” button to copy value to “Start 5DW” and “Finish 5DW” UDF.
Step 3 : Change Activity calendar to 7 Day Workweek.
You can change calendar for the first activity then use Fill Down function to apply for the rest.
Step 4 : Go to menu Tool -> Global Change.
Create a Change “LoadFrom5DW” with detail like below picture:
Click “Change” button to copy value to Start and Finish date .
Now we can see all activity Start and Finish date doesn’t change, only the Activity Duration change. Project finish Date is still 06-Mar-18
