Thank you for the interesting and detailed answer. I think there are many good points you mentioned I will have to take a closer look at. Unfortunately, I am out of the office right now and will be back again in a week and a half. I am sure that follow-up questions will arise and I would be glad if I could come back to you again. Cheers

I can edit the data manually in ArcMap and Pro. We also use the data in map services and edit them via the web browser. I'm not a DB specialist, but in my understanding, sde "only" owns the system objects. Maybe I'm wrong. TU is the owner of the user data and can therefore manipulate them. I don't know if it is a problem that TU has also "Select" but no "Insert, Update and Delete" privileges on data of e.g. AB and XY when I try to start an edit session with ArcPy.

Thanks for the fast response! I am not sure about the parameters, though. I read several times that for versioned data in a DB one should use the setting True, False. I also tried the default True, True and the opposite, False, True. Unfortunately, both without success. About the permission: I am using a connection file for a technical user (TU) to connect to the default version (owner SDE). I only want to manipulate feature classes belonging to TU, but with the specified connection, I can also see feature classes belonging to other users (without privileges to manipulate them). E.g.: - AB.parkinglots - TU.agriculture - TU.forestareas - TU.waterbodies - XY.airports and so on ... To avoid listing feature classes belonging to AB and XY, I used a wildcard in ListFeatureClasses (line 10). In the example above, it would be fcList = arcpy.ListFeatureClasses("TU".*) So, even if I don’t try to manipulate the feature classes from AB and XY, is it a problem to start an edit session and don’t have sufficient privilieges? Could that be the problem?

I would like to create a script tool to loop through feature classes in a versioned Oracle database and replace a specified value within two specific fields (if they do exist). I am quite new to ArcPy so I am sure some of the tasks could have been implemented much more elegant. Below is the code I have written so far. Unfortunately, I stumble upon the following problems: In a first approach, I used an UpdateCursor without starting an edit session and everything seemed to work fine. The problem was that changes did not seem to be permanent. I ran the script in a script tool in ArcMap and as soon as I closed the program, all changes were reverted After that, I switched to the da.UpdateCursor as it is much faster. When I run the script in PyScripter, it stops at line 20 ("for row in cursor") with the following error message: RuntimeError: Objects in this class cannot be updated outside an edit session [owner.example_edit] Next, I tried to implement starting an edit session and I get the generic error message (line 14, "edit.startEditing(False, True)"): SystemError: error return without exception set I have consulted many forum posts related to this error and have tried many different things. At one point, it even run through but stopped at "edit.stopOperation()" with the same error. Unfortunately, I cannot figure out the exact problem and I am not able to solve it. Further, but not so important, ListFeatureClasses() is very slow when I run the script in PyScripter. It takes several minutes to list all feature classes. On the other hand, if I run the same snippet directly in the python console in ArcMap, it takes only a few seconds. Any kind of help is much appreciated!
