error in AifRequestProcessor - executeServiceOperation

Hi all,

First of all, I don't have a clue about AX and I would like your expertise.

I have a problem when I consume an AX 2009 service. I'll try to explain furhter...

Aspx application calls the AX 2009 service but allways is received "Fallo en la solicitud. Consulte el registro de excepciones si desea más detalles."

When we look at AX we only find this and for me is not very helpful. "AifRequestProccessor-executeServiceOperation -> Elemento de datos CreateDate desconocido"

Could you bring me some light about this?

Thanks in advance!
