[davidsmith]

Hello,

We are curious to see how other are using the Project Calculation field in ServiceNow. What are the advantages disavantages of using Automatic or Manual Calculation? Are the are any preferences for either method, especially in regards to to the type of project being managed, if dedendencies are being heavily used etc?

Type of calculation to use for task dependencies: 

     1.Manual: Task dates do not reflect any changes made to dependencies.    

    2.Automatic: Task dates are automatically updated to reflect any changes made to dependent or child tasks.

By default : It will be automatic .

Mark correct and helpful.

When you don't want to modify the task dates based on child then keep manual.Otherwise keep automatic.

I know it's an older post but I'm having the situation that there's no difference in my instance if I chose manual or automatic. No difference at all if I make a PRJTASK in a PRJ with longer dates. Any idea what the cause could be?
