ERROR 001987: The domain is required by utility network and cannot be deleted.

Question

Hi All,

I have UN created with one domain network in it.  have few subtypes created in each featureclass with assetype of each subtype having one domain assigned. If I want to change coded description of one these domins, idelly I should do 'remove domain from field', edit+save the domain and again 'Assign domain to field' should assign it back. In reality, 'Assign domain to field' fails to assign it and throws error as below:

If I revert the changes made to domain and reassign it,it works normally which is strange.

Thanks.

I’m encountered on the same issue while documents don’t offer that much of help. For example, I couldn’t manage what to do as I got same error (001987: The domain is required by utility network and cannot be modified)

Even removing that, you will not be a leave to remove it.  It is blocked in a feature class that is part of a utility network.
