You delete a Work Order Type only if it has never been selected on an existing Work Order record.
To delete a Work Order Type, from the main menu, arrive at the Work Order Types setup with this path: Setup > Operations > Work Order Types.
The Work Order Types list opens. Locate the Work Order Type you want to delete, and then click on the Delete button.
Note: When you click Yes to delete a record, this does not delete the value from the database; Managely marks the record as “Inactive”. In most cases, if a setup value was previously marked as “deleted”, you can to re-activate the deleted [inactivated] record. When selecting to view Inactive Only records, items that were previously “deleted”, will appear in the inactive list.
A confirmation message will be displayed. Click the Yes button to proceed with the deletion (inactivation) of the record.
