E2977 Cmd Rej: Cannot leave a solitary PC in group

Point codes cannot be deleted from an MRN group if the deletion leaves only one point code in the group. If deleting one or more point codes from the MRN group leaves only one point code in the group, then the entire MRN group must be deleted.

Recovery

1. Display the MRN group that contains the point codes to be deleted. Enter the rtrv-mrn command.
2. If only one point code remains in the MRN group after the deletion, delete the entire group. Refer to the command description in Commands User's Guide and to the Database Administration - GTT User's Guide for assistance.
