I am working with SDE data running from server. I am trying to do basic edits like polygon manipulation, attribute maintenance, land cover layer edits, etc. When I try to start an edit session I always get an error based off edits with the database. I am pretty new at idea of versioning, locks, and so on and cannot figure out process to make these edits work properly and than save my data. I have tried "Registering as Versioned" and hasn't helped or not sure how to go about locks on data. Any help, tips, or advice on this subject or a walk through regarding SDE data, versioning, edits would be much appreciated.
