The GIS Export supports domains and subtypes. This applies only to the export formats pgdb und fgdb. If you need domains and subtypes for shapefiles as target format, the subtype-values are required as a table. The table can be joined to the FeatureClass via the section JoinDef in the GIS export configuration.
Note: There is a restriction for subtypes if there exists a join on the FeatureClass. The subtype-value can not be determined correctly for the joined FeatureClass. This means if there exists a join on the same FeatureClass, the subtype-value is not added to the exported FeatureClass.
