When you digitize gas network features, a feature rule sets the supply zone for a line feature if it is located within a zone. If the feature is located in overlapping zones, you are prompted to select a zone. If you select Yes, you can select a zone. If you choose No, the pressure zone value is cleared.
If you digitize a supply zone while the gas network features already exist, the pipes are not updated and do not belong to the supply zone.
You can use a feature function to update the relations. See also Connect Features to a Zone
