This request is to implement an enhancement to ArcGIS Pro to be able to join, relate, or whatever process is necessary, data from different data sources and publish it as a service to be consumed in a web application while still allowing the data to be dynamic, reading from the data sources.
Currently, ArcGIS Pro cannot publish a service to ArcGIS Enterprise while an in memory join is present. However, this function can be critical when needing to link to different data sources (feature class and tabular data). For instance, if the tabular data is part of a mission critical read only system that is dynamic that the user would like to connect to a feature class and bring into a web mapping application. I have also tried creating a relationship class but that cannot be created on a view.
