Document Data source in the excel addin doesn't show up

Hi, I am trying to use the excel add-in to import data into AX. I created the AIF inbound ports and added services for accounts receivable, accounts payable etc., Also added the document data source for Account receivable ‘CustCustomerService’ etc.,

When I open Excel, I am able to set up the connection and add table. However, when I try to add Data (none of the data source are showing up that I set it up in the Document Data Source). Another issues is that the surrogate/replacement not present error. I really need to see the data source and appreciate if some one can point out what is the issue.

Thanks a lot.
