Failed to execute (AssetPackageToUtilityNetwork).

I am using Utility Network Data Management  implementation pattern stated in Implementation-Patterns-for-UPDM-2019. When I run the Apply Asset Package tool to load schema only, it fails with following error:

EXCEPTION

Can you post the parameters and full messages from the run?  I think we know the issue, but need some more information to be sure.

[aaizMe]

Thanks for the reply. In asset package I am giving the changed asset package according to my spatial reference system and in utility network(UN) parameter I am giving test_ne UN. test_ne has only StructureLine. 

[MikeMillerGIS]

If you check both Structure and Pipeline in Apply Asset Package, do you get the error?

[aaizMe]

It worked but completed with warnings. Also do I have to delete the extra feature classes?, for example the data I have won't have linear referencing, P_Centerline, P_CenterlineAccuracy etc. Do I need to delete these feature classes?

Linear referencing objects/attributes may be left in the model with no data. It is a good design practice to envision the capabilities/requirements for the implementation.
