I have Portal for ArcGIS and ArcGIS Server 10.5 federated. I have published my feature services using ArcMap 10.5. I have developed an application using web app builder. I want tool to extract data on my map in different formats. Somehow extract data under analysis seems not working for me.
Because there is an OTB widget for this no one has developed a custom one. You need to work with Esri support to figure out why the data extract widget is not working for you.
