Subtypes are dropped after running the Sort geoprocessing tool in ArcGIS Pro.

解决办法

Use the Transfer Geodatabase Field Properties environment with the Sort tool to transfer subtypes and domains. This is not on by default due to performance loss when performing the transfer. Refer to, https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/sort.htm and https://pro.arcgis.com/en/pro-app/latest/tool-reference/environment-settings/transfergdbattributeproperties.htm for more information.
