I have migrated a Filemaker Pro database to an enterprise geodatabase in SQL Server Express so that it can be viewed/edited in both Filemaker Pro and ArcGIS. I'd like the ObjectID field in both feature classes and stand-alone tables to auto-increment when new records are added in Filemaker Pro. I thought I could do this using the Identity data type in SQL Server but it does not appear that this data type is supported in ArcGIS (http://support.esri.com/cn/knowledgebase/techarticles/detail/40329). I also don't appear to be able to alter this field in Filemaker to make it auto-increment. Just wondering how people deal with this - is manually entering the value the only way to update the ObjectID field outside of ArcGIS? This doesn't seem ideal. Thanks in advance for any help!
