I have a geodatabase feature class that has domains. I have extracted a portion of this feature class and manipulated some of the data within and then appended the data back to the original source. When I append the data the numerical information in the attribute table for the appended portion is lost and replaced by null values.
I have tried to export the portion I need to work on as a shape file and also as a feature class into the same geodatabase. I get the same issue in either case. I was wondering whether the issue with the null values is because the domain for the data fields is lost once I export? If I export the original data and the portion as a shapefile and then merge there isn't an issue. However, I need the domains used in the geodatabase.
Any help appreciated. Thanks
Domains are a property of the geodatabase, not the featureclass. When you append the extracted data back into the original database, have you deleted the orginal features? I ask only because if you have not, you'll end up with double entries. I'm not a big fan of the append tool. Must have had a bad experience at one time or another. Try using the simple data loader. I also have to ask, why not just perform your manipulations on the original features in the original geodatabase?
Just realized I read to quickly, you do seem to be manipulating numeric values outside of ArcGIS, so they should be able to import. What software are you using to edit the exported data? Can it be that it changes the field type? You might check this by looking at the properties in ArcCatalog.
