When adding or editing RPP, if there is a conflict with the HN layer (i.e. too far), then the WME issues an error that prevents you from saving your edit. Thus, you cannot add or update this RPP.

To resolve the issue you need to perform the following steps:
1. Update/Remove the address in HN layer
2. Wait for next (successful) map build
3. Add the RPP

This is an annoying procedure that should and can be avoided.

The issue can be handled in one of the following ways:
1. Verify the RPP against the most updated data either in the edited or production HN layer databases.
2. Allow conflicts. Issue a warning but allow to save (rank depended). The same as forced HNs are allowed. Especially that for navigation, exiting RPPs are used before HNs.

The above suggestions or any other solution that will allow immediate RPP editing would be very welcomed.

I prefer option 1, as it also solve the conflict.
