# Create a data refresh rule for a non-CMDB table

To apply Identification and Reconciliation Engine (IRE) features to supported
non-CMDB tables, create data refresh rules for those tables. Data refresh rules are used to
determine if a record is stale for a specific data source. Such records can then be updated
by a lower-priority authorized data source.

## Vorbereitungen

Role required: sn_cmdb_editor and itil have read access, sn_cmdb_admin and itil_admin (on top) have full access

## Warum und wann dieser Vorgang ausgeführt wird

Data refresh rules have no impact when dynamic reconciliation rules are in
effect.

Data refresh rules are used in conjunction with static reconciliation rules to determine reconciliation steps for a record. These rules determine if, when, and by which data source a record can be updated.{#create-non-cmdb-data-refresh-rule__ph_DataSourceRefreshAbout}

## Prozedur

1. Click All.
2. In the Filter navigator, enter <kbd class="ph userinput">cmdb_datasource_staleness.list</kbd> to open the Data Source Staleness Definitions table.
3. In the Data Source Staleness Definitions list view, click New.
4. Fill out the Data Source Staleness Definitions form.  
   {#create-non-cmdb-data-refresh-rule__table_ypd_12f_z1b__entry__2}

   | Field | Description |
   |-|-|
   | Applies to | Non-CMDB class that this rule applies to. |
   | Data source | Data source for which record staleness is evaluated. |
   | Effective Duration | The time period that is used for the staleness evaluation. If the fields specified in the static reconciliation rule for the record's class were not updated by the specified data source within the specified time period --- the record is determined to be stale for that data source. If you enter a value with a prefix that is valid and a suffix that is not, such as <kbd class="ph userinput">15 x</kbd> --- the valid portion of the value is used ('15'). If the entire value is invalid --- the default value of 0 is used. |
   | Active | Activates the rule. |
