You should reconcile every time you get done transacting map actions or make any changes to your edit financial information. Essentially reconciling is taking all the real information you put into the system and using that data to come up with new map actions and updated information for you. Reconciling often keeps your plan up to date and working efficiently. The longest you should ever go is 45 days. This is because only 45 days of MAP actions are created when you reconcile.
