arcpy on ArcDesktop 10.3 issue with assigning domains to fields

Question

I have a python script I wrote that reuses domains. I had no issues with 10.2 but just upgraded to 10.3 and now the script throws an error (see below) if I assign the same domain to multiple fields in the same feature class. Any suggestions other than the obvious fix of creating a new domain for each field?

"ExecuteError: ERROR 999999: Error executing function.

Item relationship between the items already exists.

The operation was attempted on an empty geometry.

Failed to execute (AssignDomainToField)."

Thanks,

Chris

Hi Chris Mowry,

See the below code & Image For one Feature class & subtypes AssignDomain to Field.

import arcpy
arcpy.AssignDomainToField_management("WS_Fitting","DIAMETER","CD_Diameter",["1: 11 Bend Fitting","2: 22 Bend Fitting"])

Thanks

I am not sure if this is still valid, but I was having the same issue in 10.4.1. I found that I had to Assign the Domain to the field first, then I was able to add the Domain to the SubTypes (this seems to also go for when you need to delete a domain associated with SubTypes). So in you sample code you would need to add an initial AssignDomainToField just for the field. See second line below: subtypeVal = [1,2,3,4,5] arcpy.AssignDomainToField_management(FeatureClass, Field, Domain) for value in subtypeVal: try: arcpy.AssignDomainToField_management(FeatureClass, Field, Domain, value ) except: pass‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I have the same problem on a 10.3.1 environmemt

I found out that your "try ... except" is not a good workaround because a sync-enable feature service published from "that" FeatureClass seems to give a corrupted SQLite goedatabase replica (Invalid XML if you catch the OpenAsync of a SQLite offline gdb via Runtime SDK).

Has anyone found the same connection from this error and the offline SQLite gdb InvalidXML error?

Does anyone knows what "Item relationship between the items already exists" exactly means?
