I tried to publish a dynamically generated layer as a map service. This dynamic layer is generated through a ModelBuilder that consists of a Add Join tool. In the map service publishing, I received the error: 00099: Layer has a join with an unsupported data source. I believe that that is due to the use of an In-Memory FC (unsupported data source). Through google, I could not find any discussion to avoid/eliminate this problem. Do you know how? Appreciate if you can share your experience.
