Software version: ArcMap 10.5

I am attempting to append data from a Shapefile into an existing SDE Geodatabase feature class using the Append (Data Management) tool. The tool runs, and the results say that it has been successful and no errors are shown, however the point geometry and attributes are not shown in the feature class.

I have tried in both an edit session and not, and using NO_TEST to map the attributes. I cannot see any reason why it wouldn't work.

What am I doing wrong and are there any alternatives to this tool if it is a known bug?

    Try exporting the shapefile to a File Geodatabase and use the feature class in Append tool – BERA Mar 31 '17 at 9:30

    Is the target feature class versioned? How are you determining that the data hasn't been added? – Vince Mar 31 '17 at 11:08
  • Same as monkeyshines. While working on my office's network drive, while trying to append two features in the same geodatabase, the append populates all records with <null>. At this point I've tried refreshing the gdb and tried removing and adding the feature again to no avail. However, when I work on my local drive, all field are populated correctly. Would be nicer if it worked on our network. – JKeeley Nov 15 '18 at 16:21

Try exporting the shapefile to a File Geodatabase with Feature Class to Feature Class tool and use the feature class in Append tool. When a geoprocessing tool fail with shapefile input it will sometimes work with a feature class input.


I was having this issue as well. In my case I was appending points. The tool ran successfully yet the new records did not appear in the target feature class. I refreshed the map and still nothing. I removed the target feature class and added it again then what do you know the appended data was there. ArcMap has a hard time refreshing so refresh your GDB or remove/add your shapefile and the data may be there.

  • This was my solution to this same problem. Refresh the database connection and re-add the feature class. – CStarbird Jun 5 '19 at 21:06

I have also experienced this problem; here is my $0.02.

The cause in my case, as far as I can tell, is that the datasets I was trying to manipulate reside on my local NAS. After testing variables such as projection, field mapping options, et cetera, I copied my input and target datasets to my machine's drive, and lo, it worked.

BTW, the input was a .shp and the target a file GDB feature class. This did not appear to be an issue.


Be sure that there are no definition query's enabled on the target.
