Lately we encounter problem when integrating CRM connector with Dynamics AX 2009 EE layer. While running map AX Enumerated Values to Picklist you getting error in CRM Connector.
The map does not synchronize correctly and the values are not available. To overcome this issue you need to install hotfix for EE GLS layer. The KB article number is 2778999 and should available soon.
If it is still not available please contact Dynamics AX support team.
