Is there any way to filter on the map for the eo attribute D_ID_CONFIRMED_ID?
Please see the Join Additional Oracle Fields help topic which describes exactly how you can add your desired fields for use in the Map with Identify, Feature Search, Filter, etc. Via this tool you are empowered to do so yourself!
You can easily make it a less ephemeral solution by creating a Saved Map once you have created the Join. That way, you merely need to load the Saved Map upon opening the Map in order to have it available to you. Simple solution!
We have had many requests for various fields that different programs feel would be beneficial. It was agreed by all that implementing this solution would be much better as it lets the individual user decide which fields are necessary. Additionally, by implementing this solution, additional development work is not necessary every time someone decides a different field is critical for their work.
