Error: The Replace feature operation failed (feature class name : ObjectID)
During conflict resolution, the following error is returned with the feature class name referencing the orphan junction feature class:
"The Replace feature operation failed (feature class name : ObjectID)"
The replace operation attempts to create an orphan junction coincident with a user defined junction; this is not allowed.
Solution or Workaround
Avoid resolving this conflict. Since orphan junctions cannot subsume or replace user defined junctions, the error is valid. If trying to resolve all conflicts for a given feature class, perform conflict resolution at the feature level.
