How to merge a featureClass with an already published Feature Class in ArcGIS PRO

[AngelRomoSandoval]

Hello, I hope someone could help me:

This is my method:

In Ausgabe-Dataset ("Output-Dataset") I insert the name of the existing already publisched FeatureClass but It creates a new FeatureLayer in the map instead of joining with the existing.

I think you're using the wrong tool.

Merge combines multiple input datasets into a single, new output dataset.

You want to use Append, which appends a dataset to an already existing one.

Also, make sure that you published with permission to edit the dataset, or append to the "original", unpublished feature class. The edits should show up in the published service, too.

Totally useful, thank you Johannes!
