# Set recommendation criteria

# Create the principal class recommendation criteria property {#ariaid-title1}

Release version: Australia

![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Create the sn_cmdb_advisor.principal_class_recommendation_criteria system property to filter which CI classes CMDB success advisor considers when generating principal class recommendations for the Data Foundations advisor.

## Before you begin

Role required: admin

## About this task

This property does not exist by default. Without it, CMDB success advisor generates recommendations based on CI class activity in task records. Create this property on instances with no prior task activity, where task-based recommendations produce no
results. Setting the value to `PREDEFINED` tells CMDB success advisor to recommend a standard set of commonly managed CI classes instead.

## Procedure

1. Set the application scope to CMDB success advisor using the application picker.
2. In the navigation filter, enter <kbd class="ph userinput">sys_properties.list</kbd> and press Enter.
3. Select New.
4. Fill in the following fields.  
   {#cmdb-sa-df-rec-criteria__table_set_rec_criteria__entry__2}

   | Field | Value |
   |-|-|
   | Name | sn_cmdb_advisor.principal_class_recommendation_criteria |
   | Type | string |
   | Value | `PREDEFINED` Tells CMDB success advisor to recommend a standard set of commonly managed CI classes: Computer \[cmdb_ci_computer\], Server \[cmdb_ci_server\], Database \[cmdb_ci_database\], Cloud Database \[cmdb_ci_cloud_database\], and Virtual Machine Instance \[cmdb_ci_vm_instance\]. |
   [ ]

   {#cmdb-sa-df-rec-criteria__table_set_rec_criteria}
5. Select Submit.

## Result

CMDB success advisor uses the predefined set of CI classes as recommendations on instances where task history produces no results.
