Error while exporting Route data from AX using DIEF

Hi,

I want to export Route data from AX and store it in a CSV file.

I’m using the Data import/export framework in AX2012 R2 for exporting.

I created a source data format of type “AX” and created a processing group with the “Route” standard entity and used the “AX” source data format in that processing group.

On clicking the "Get staging data " for that processing group im getting the below error.

Please guide.

Thanks & Regards,

Chutti
