Troubleshooting a mapping

Review the rules and guidelines for configuring a mapping.
I made a lot of changes to source field metadata that I want to revert. I tried the Synchronize icon, but nothing's happening. What's going on?
Synchronization does not restore field metadata that was updated in a Source transformation. You can manually update the field metadata. Or, you can start over: Clear and select source object or create a new Source transformation.
A field name conflict error message displays in a transformation. In the transformation, I created a field rule that renamed the incoming fields, but the error continues.
A field name conflict can continue throughout a mapping after the initial problem. Locate the transformation with the first field name conflict error message and rename the fields before they enter the transformation.
