Not applicable to tables. Applies only to view fields.
Check the Update Lock check box to prevent a view field’s Properties, Integrity, Code and Help entries from being updated when the Update Field Info utility is run. See Update Field Info - Views.
The Update Field Info utility copies the Data Builder Field entries for a view’s associated tables to the Data Builder field records of the view. If you have made Data Builder entries for a view field that differ from the field’s Data Builder entries for the associated table, you will not want the view field’s different entries to be copied over if you run the Update Field Info for the view. The Update Lock field property lets you lock a view field’s Data Builder entries so that they cannot be changed by the Update Field Info utility.
