An alert message is generated if the matched data indicate that GPO should be imposed
                  or adjusted.
               
               The OPM/GPO enforcement alert message generates for a spouse’s MBR record if the OPM
                  record shows a pension being paid, but the MBR shows no GPO data.
               
               The CA will determine if offset applies and take the following actions:
               If the claims file shows that GPO does not apply, instruct the BA to post a CSGPO
                  of “N” to the MBR. This action avoids another alert.
               
               If offset is imposed correctly, instruct the BA to update the GPO data to the MBR.
               In all other cases, take the following actions:
               
                  - 
                     
                  
- 
                     
                        • 
                           Diary and control for 35 days.

                        • 
                           If no protest is received (when the diary matures), instruct the BA to impose the
                              GPO and post GPO data to the MBR.

                           If a protest is received, instruct the FO to resolve the situation per GN 03001.025. Diary the case for 30 days.
