Data Migration Framework for Employee Entity for updates.

Hello All,

Question: How can I UPDATE exisitng employee records using DMF for the Employee entity.

Background:

I have installed and configured the new DMF (beta) for migrating (in our case UPDATING) Employee information from a .csv file into Ax 2012 instance. I can get data from my sample file into staging no problems. BUT, when I try 'Copy data to target' it fails saying that the employee record already exists.

I'm trying to update existing employee records. is this acheivable with DMF?

thank you,

Boubacar
