Overwriting original layers

Winter_Widdifield

I am currently working on a web map that will be used in the instant app attachment viewer. A map was created last year, and I want to use it as a backbone for my map this year, but replace the attachments. I tried saving the map from last year as a new file, and the layer I am editing the attachment of as a new layer all together by using "save as", but for some reason it is still overriding the original feature layer. This is a problem because the map from last year is still used and referred to, so I do not want anything on the original map to be updated. Is there something I'm missing? Thanks!

Hey @Winter_Widdifield 

When you use "Save As" on the map, it's creating a new instance of a map, while using the same original Feature Layer, so any changes you make will reflect on all maps that use the Feature Layer. You may want to create an export of your Feature Layer to test with it being disconnected like these steps outline:
