Dynamics Connector: Mapping currency information

Hello!
I have some trouble with configuration "Connector for Microsoft Dynamics" between Microsoft Dynamics AX 2012 R3 and Microsoft Dynamics CRM online 2015.
For instalation I used installation guide "MSDynConnectorAXconfig.pdf" from www.microsoft.com/.../details.aspx
The problem arose at step "Mapping currency information"- It didn't find any values to send from AX to CRM.
I spent a lot of time to solve the problem, but I can't find any information for it.
Also I can't find anything to explain me how I can saw from what table connector take data to CRM.
Can you tell me what can be explained by the fact that the data can not be detected?
