You may want to modify your CP systems for a variety of reasons. The CP system status icons in the All Systems view provide a means of determining which systems are unprotected, out-of-date with gas or water network data, or both.

You are responsible for maintaining your CP system data. It is possible to use this tool to create orphan CP systems. View the Redefine CP Systems help topic for more information about correcting your CP system data. |
- Click Cathodic Protection Systems on the ArcFM Gas Traces
or ArcFM Water Traces toolbar 
.
- Use the right-click navigation commands to visualize a particular CP system.
- Edit the map to make changes to one or more of the features that belong to a CP systems.
 |
- In general, you should only edit the gas or water network features that belong to the CP system, and not the features in the special CP system feature class (which do not belong to the gas or water network). DO NOT directly edit the Shape of features in the CP system feature class. Doing so prevents proper functioning of the autoupdater that maintains the RefreshNeeded field, causing problems with CP system status updates. Most other fields in that feature class, including Shape, are assigned automatically by the CP tools in ArcFM. In the Minerville sample data, this feature class containing CP system geometry is called CPSystems.
- With the exception of custom fields you may have added, the Name and Technician fields are the only fields in the CP system feature class that you are encouraged to edit. All other fields in that class are automatically assigned values by tools in ArcMap. Immediately after you edit the Name or Technician fields using the Attribute Editor (or Attribute Table), click Cathodic Protection Systems on the ArcFM Gas Traces toolbar or ArcFM Water Traces toolbar to reload the tool. This helps you avoid overwriting the changes via the tool's Update Status button.
- If you undo edits or stop editing without saving edits, do not rely on the Update Status button in the All Systems view to generate an accurate representation of current map data. Instead, close and reopen the Cathodic Protection Systems tool.

- Double-click the zone to which changes were made and click Save
.
|
Only the traced features highlighted in the map will be saved. If you have added new features to the CP system after accessing its system-specific view, do not click Save. Instead, return to the All Systems view and again double click the modified zone. The new CP trace will discover the features you added and highlight them in the map. Now when you click the save button, the new features will be saved to the CP system table. If you click Save before conducting a new CP trace, the CP system will save only what was originally traced and remove the Not Current status. That will prevent the Cathodic Protection Systems tool from discovering the features you added. |
