Dynamics Connector Maps for Currency, Product, and Customer

I’m encountering a few, but similar issues with out of the box maps for Currency, Product, and Customer.

It could be a flaw with the design of the connector, or limitation of AX/CRM integration.

In general, the issue is when some details are updated in AX, the changes are not detected/brought across by the connector to CRM.

1) Currency – when an exchange rates is added/modified in AX, the change isn’t reflected in CRM. I believe this is because the change is in table ExchangeRate, and the connector monitors changes in table CurrencyPair.
2) Product – when the on-hand inventory is updated for a product in AX, the change isn’t reflected in CRM. Again, I believe this is because the change is in a separate table, and the connector monitors changes in table InventTable.
3) Customer – when E-mail address or URL is added or modified, the change isn’t reflected in CRM. Like above, I believe this is because the change is in a separate table and the connector monitors changes in table CustTable.

Can anyone think of a workaround/solution to these problems? The connector needs to monitor field ModifiedDateTime of the related tables, not only the main table.
