The deletion of structure identifiers is only possible if they are no longer used as page identifiers or on devices. (Such identifiers have the value "No" assigned in the Usage column of the dialog Structure identifier management- <Project name> as soon as you have selected [Extras] > Check usage.)
Notes:
- Alternatively to this procedure you can also remove structure identifiers no longer in use from the database globally with [Extras] > Clean up all.
- If you attempt to delete a structure identifier that is still in use in the schematic, a message appears to that effect and the action is canceled.
- If a page or a device is deleted whose structure identifiers are not used in any other place in the project, then this identifier is still not removed from the database. Deletion of structure identifiers is only possible in structure identifier management.
