ORA-42914
An existing data label cannot be changed to a user-only label.
Cause
An existing data label that is available for data and users can not be altered to only be a user label.
Action
Review existing labels in DBA_SA_LABELS. The LABEL_TYPE column defines if the label is used as a data label. Determine your requirements and:
- Run the same operation but use NULL for the new_data_label parameter.
- Create a new label that will only be a user label.
