Deleting the Values of a Custom Segment
In some cases, you may need to delete one or more of a custom segment's values. You can delete the values of a segment in two ways:
You can't delete a value if that value has been saved on an instance of a record. If you try to delete this type of value, the system displays the following error: The segment value cannot be deleted because a child record exists.
Instead of deleting a value, consider it inactive.
If a period is closed, you can't change custom segment values that impact GL on any transactions in the period.
