Out of the box there are 5 of those Custom Profile Properties (Data Members) to map custom user profile properties to. I know that I am going to need more than 5 of those. What is the proper way to add a new data member, say 'Custom Property 6' (u_Pref6), to the Commerce Server Manager User Object and then be able to use it in the Customer and Order Manager?
I tried doing this myself and I got an error when I tried to create a new profile in the customer manager with this newly modified profile definition. I was able to get the new custom property added to commerce server manager and I was even able to get the field to show up in the Customer Manager thanks to Nihit Kaul's post regarding how to do that. I was just unable to create a new profile in the Customer Manager after adding the new data member and tying a custom user object property to it. I feel pretty certain that the error was due to me not setting up the new Data Member correctly.
According to Jeff Lynch and my own experience, you must manually add the columns you need to support your custom profile properties to the 'userobject' table in the Profiles Database in order to store those values. This is the same procedure used in Commerce Server 2002.
