could anyone help please
Thanks!
Hey @MaryamAlHefeiti
I'm curious if you've attempted these steps in this document here?

@MaryamAlHefeiti You're copying data from a simple feature layer to a geometric network layer. The geometric network imposes additional restrictions (like the one outlined in the KB article Cody referenced). You'll need to find and repair any features with the same location for their start/stop vertex.
