::Hey Kevin,
It’s unfortunate that nobody has replied with expertise in rebuilding your Data Mart.
I can offer this advice… I use the legacy connection (of Management Reporter to GP). It’s a direct connection to the SQL database. I do not have to worry about keeping anything synchronized, making it easier to maintain without losing any functionality (financial reporting).
Others may suffer some loss of functionality if they give up their DataMart. Not us.
You shouldn’t have any trouble finding documentation on the legacy connection and you should be able to find it easily in the MR Configuration Manager.
I hope this helps.
Chris
