Publish DGN File on Portal

[MatsHardy]

I have setup a ArcGIS Portal 10.5.1 server years ago. Recently, I have received a MicroStation DGN file and wants to publish it as layer on Portal. I have tried to convert the DGN to gdb and shapefile. Even I can published the converted gdb and shapefile to Portal. When I added the published layer to map, I cannot see the layer. Anyone has Idea?

I have just figured out what happened. The gdb generated from DGN does not have spatial reference. User need to set it manually. After spatial reference is set, the gdb can be published to Portal and shown on map.
