Below is a screenshot of my workspace that creates a new feature class (AttributeManager_6_Output). This feature class will be edited by end users in ArcGIS Pro. I need to bring that feature class back into the workspace and join it back to caputure those edits. My problem is that some of the attributes will be updated upstream as well. I need to capture those edits as well without overwriting the end user edits. How am I able to set the attribute conflict independently (some attributes from Left and some from Right) in the FeatureJoiner?

    Hi ​@michaelmessing,

    Thank you for posting your question on the FME Community, and apologies that we missed your question!

    Unfortunately I don’t believe the FeatureJoiner doesn't support per-attribute conflict resolution. To work around this, you could run two joins with one preferring Left and one preferring Right, then use an AttributeManager to pick the specific attributes you want from each result and combine them into your final output.

    Let us know if you still need help with this!

    Are you using a join method in the FeatureJoiner that can only be achieved with the FeatureJoiner, or could you use a FeatureMerger instead? That will then give you the option to prefix attributes from one side of the join and then you can handle renaming as appropriate separately.
