CMDB Ci reference qualifier

[RushithaD]

I do have  requirement where when i click the ci in any incident, problem and change request , it should only show the principal classes. Need further details on what filters are applied for Configuration items 
Where the OOB reference qualifier is working  in PDI where as it is not working my company instance, where both reference qualifier are same, not sure, in the PDI it is displaying all the records where in the company instance. There is 19.9M CIs in CMDB_CI table but only 7.2M show here

@Ankur Bawiskar Can you please help me or explain how the OOB reference qualifier works

javascript: ['incident', 'problem'].indexOf(current.sys_class_name + '') == -1? '' : 'operational_statusNOT IN' + new OpsStatusFilter('cmdb_ci').by('CreateTask').join()

in the incident or task table.

@RushithaD 

the OOTB works like this

if the current table is incident or problem then it excludes CI records whose operational_status is in the list returned by new OpsStatusFilter('cmdb_ci').by('CreateTask').join()

for any other table it returns an empty qualifier, meaning no extra filtering

Hi @RushithaD 

Refer post : I Want to show the list of principal class CI's in the configuration item field in incident, change

• The System property com.snc.task.principal_class_filter dictates which task types utilize this restriction. You need to add incident, problem, and change_request to this comma-separated list.
• CIs that are marked as Non-Operational (like in maintenance, decommissioned) should be filtered out
• The OOTB reference qualifier script is

                  javascript:new TaskUtils().getConfigurationItemFilter(current);  

              which ensures that the selected CIs are valid for the specific service management task

• Only CIs where Active = true are available for selection. Retired or disposed CIs are automatically excluded.
