When you manually run a transfer or your schedules are running based on specific interval, you might run into this error message:
E2006 - ECE_FieldTypeNotSupportedForSourceControl

Source Control


This error message indicates that the field that is being used as a source control ( Open the transfer that is displaying this error -> Go to the Source Control section -> Source Control Field) is not supported and you will need to use timestamp fields or datetime fields as source control fields. 
You would need to do the following: 
1) Click on the Pencil icon and edit the Source Control Field by removing the one that is currently used and causing the error message, then click on Save and afterwards on the Activate Changes button ( at the top of the transfer page); 
2) Replace the current source control field with another one, click on Save and then Activate Changes.
