Trying to merge 2 geometric networks with Incremental network loader I got this error -error picture

How can I find this Closed polylines at my geometric network ?

A polyline is closed if from and to points are the same. So you could test this in a new field:

field calculator : Python

codeblock

def IsClosed(shp):
    if (shp.firstpoint.x == shp.lastpoint.x) and (shp.firstpoint.y == shp.lastpoint.y) :
        return 1
    else:
        return 0

result

IsClosed(!Shape!)
