I have a Network Dataset with turns and need to edit some of the edges (I found out some were not planarized yet). Using the Populate Alternate ID Fields tool I keep getting the Error 030030.

The Editor is off and no feature class is in use. I get the error both in ArcMap and ArcCatalog.

  • Do you receive the same error if you close both ArcMap and ArcCatalog and then try again? And is the Network Analyst extension checked out?

  • Yes, restarting the software doesn't help. I think the Network Analyst is checked because otherwise I would not see the Network Analyst toolbox?! (don't have access to computer right now but will doublecheck on monday)

  • I keep getting the Error even with Network Analyst Extension unchecked.

I got an answer from Esri with the following workaround:

Add the alternate ID fields in the turn feature class manualy before running the tool: Add fields with names AltID of type Double for the maximum number of edges that you have per turn. This way the error does not appear.
