000464: Cannot get exclusive schema lock. Either being edited or in use by another application or service.


More than one user may be viewing and editing the same data at the same time. This can include being used by services.

To complete the operation, the application must obtain an exclusive lock. This means that the schema is fixed and will not change while you are working with its contents.


Ensure that you are the only one using the dataset and retry the operation.
