Error on Retail AOS profiles

Hi All,

I am receiving ‘LogonSystemChangedException’ error while clicking ‘Test connection’ button on Retail AOS profiles form(Retail àSetup à Retail Scheduler à Channel integeration à AOS profiles)

Attached the error image below

I am using AX 2012 R2 Retail and has all the required setup correctly.

Microsoft.Dynamics.Retail.StoreConnect.Request.AXHandler.SCAXRequestHandlerException: AX source request handler failed to process request: AX Managed Interop failure. ---> Microsoft.Dynamics.AX.ManagedInterop.LogonSystemChangedException

   at Microsoft.Dynamics.AX.ManagedInterop.Session.Logon(String company, String language, String objectServer, String configuration, String applicationObjectLayer, String applicationObjectLayerCode, String tenant)

   at Microsoft.Dynamics.AX.ManagedInterop.Session.Logon(String company, String language, String objectServer, String configuration)

   at Microsoft.Dynamics.Retail.StoreConnect.Request.AXHandler.SCAXSourceRequestHandler.ProcessSourceRequestHeader(ISCSourceRequestHeader sourceRequestHeader)

My intial observation shows service account used for business connector not having access to AOS.

Any other thoughts on this highly appreciated.

Regards,

Ganesh
