ERROR

Build Geometric Network failed. The value of the subtype code is NULL

Last Published: April 25, 2020

Error Message

During building of a geometric network, in either ArcCatalog or ArcMap, the following error message is raised:

"Build Geometric Network failed
A failure was detected inside the topology engine overlay processor. [error id: -2147220465]
The value of the subtype code is NULL.[(class name: <objectclass_name>, oid: <ObjectID>)]"

Cause

The feature identified by the error message has a subtype value of null. Null subtype values are not supported by the geodatabase.

Solution or Workaround

If a subtype field is defined for a feature class, each feature in that feature class must have a valid subtype value. Features for which a valid subtype value does not exist will cause the build/creation of the geometric network to fail.

Instances may arise where features do not have a valid subtype value. A new subtype value can be added to act as a placeholder for the null field value. Depending on the subtype values already in place, the new subtype value could be 0, 1, 9999, etc. Creating the new subtype and assigning it all features with a Null subtype allows the geometric network build process to proceed.
