Hi,
I have created Utility network and Branch version in ArcGIS Pro 2.5.
I am unable to find the Validation capability option in Configuration tab on while publishing as Web Layer.
I am using ArcGISPro2.5 and ArcGIS Enterprise 10.8 Federated Environment,Database SQLServer 2016
Please find the attached screen short for your reference.
