Hi,

The 'default contact' sets the person so that the comp_primarypersonId is their pers_personId. This means that they are shown on the summary page: -

This in the database is shown as: -

So you can see the comp_primarypersonId and the pers_personId are the same. The person to company relationship is one to many. The primary person to person is 1 to 1. This means on the summary screen you get: -

It is worth bearing this in mind when writing report views etc. as to make the choice which field you join on.

The default contact for accounts, relates to which person has the default role. I am guessing you are using Sage 200? If so, here is how it works, if not, ignore this bit!

In Sage 200, you have a default contact for the account: -

If you change the 'default for accounting' in sage 200, then integrate, this changes the default role, over to the contact you have asked it to, and they become the default.

Hope that helps.
