Update Data That Belongs to Topology

[JoshBillings]

Hello,

I am looking to update data of a feature class that belongs to a topology. I am using a basic Truncate and Append Python script to do this. I have tried TruncateTable, DeleteRows, and DeleteFeatures to delete features but I get the error: ERROR 001395: Operation not supported on a feature class in a controller dataset.

Is there a way to do this?

Thanks,

Josh

Hi @JoshBillings ,

Truncate operation is not allowed on controller sets.

Since the delete rows does not mention the same constraint as Truncate, have you tried performing the delete process via GP tool? Wondering if this works in general.

I can confirm that using the Delete Rows gp tool followed by Append gp tool worked for me. Not sure if doing this via a script would result in an error as @JoshBillings seemed to experience.

For me it worked to remove the topology.  (Obviously that's not a workable solution for every situation.)
