GP Data Mart Integration - Timeout Expired

Hi,

Using Management Reporter 2.0 RU4, we are trying to add a Dynamics GP Data Mart connecting to a GP 2013 environment.  We are able to successfully add the ERP Integration however the Initial Integration continues to fail with the error message below.

Any ideas to get around this integration issue?

[GL Transaction to Fact] has encountered an error. Processing will be aborted. Error text: Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.
