If you use FocalPoint and Dimensions, Cost Centres can be setup in either application. However, the FocalPoint Cost Centres can have more field values available so it is best to decide which point of entry is best for your company or organisation.
To set up a new Cost Centre in FocalPoint:
Log into the FocalPoint website
Click Job Costing, Project Management
Edit the relevant Project record
On the Cost Centres tab, click New.
Type all the required details of the Cost Centre
Click Save and Close.
