From Pro you can publish your web layer.
You can then customize and publish your web map from Pro.
However, is there a way to make changes to the Web Map in Pro and then overwrite what is already there without having to delete it first?
Hi Robert - see this thread You can up vote but more importantly, please comment about what changes in the web map you expect to make. It seems like the majority of users simply want to update symbology, but there could potentially be many other changes made to a web map opened in Pro and we are interested in better understanding user needs and expectations.
I have the same question, I need to update the symbology of the map... a map that I have used to create some dashboards and if I cannot overwrite it, I will have to delete. and publish it again... but this will break all my dashboards.... !! What do I should do??
I'm using web maps for my asset management system. When I want to make a change to a layer, TOC order, etc. I would like to click a button to overwrite similar to the Web Layer. The content management of the layers for my asset management system can be utilized in Cityworks backend using REST endpoint services directly or within ArcGIS Portal in web maps. I suspect that long-term, managing the content within web maps will provide me greater functionality. I need the overwrite web map tool to make this a reality
One more critical point that I forgot to mention yesterday is the ability to maintain a static web map ID in Portal. I have my asset management system setup to use these web maps and have to list this specific ID in the web maps URL. If I delete and then recreate, I have to constantly update my web map IDs in my asset management system. Instead, if it could maintain the same web map ID that would be great.
