A CI relation rollup allows you to sum, count, max, min, or mean a relationship type.
You can create CI relation rollups.

## Vorbereitungen

Role required: ecmdb_admin

## Warum und wann dieser Vorgang ausgeführt wird

CI relation rollup can be useful for tracking and for receiving notifications. For
example:

* In a sum roll up, add up fields from multiple CIs and display the result on another CI to which they are related. So, if you have four configuration items in a rack that are all consuming power, create a CI relation rollup to add all the power usage together and display the result in one field on the rack CI form.
* If a certain level of power consumption in a rack is exceeded, send a notification.
* With a rack that has 10 slots, send a notification when 9 slots are filled.

{#t_CreateACIRelationRollup__ul_ul1_zq5_4q}

CI relation rollups use the cmdb synch event business rule on
the \[cmdb_ci\] table. Although this business rule is active by default, you must
modify the rule slightly before it will run.

## Prozedur

1. Navigate to AllConfigurationRelationshipsCI Relation Rollups.
2. Click New.
3. Complete the form.  
   {#t_CreateACIRelationRollup__table_tlh_bt5_4q__entry__2}

   | Field | Description |
   |-|-|
   | CI Relationship Type | Select a relationship type from the list to use with the rollup. For example, Members::Member of contains the parent descriptor Members and the child descriptor Member of. |
   | Type | Select the type of rollup from the drop-down list: COUNT, MAX, MEAN, MIN, or SUM. |
   | Parent field | The target field on which the operation will be done. |
   | Child field | The input to the equation type. The Parent field is affected by the selections in the child field. |
   | Rollup class | The classes that can use the relationship. For example, you can specify that the relationship only applies to racks. |

4. To run the cmdb synch event business rule, navigate to Business Rules.
5. Use the search box to find the \[cmdb synch event\] table.
6. Click the cmdb synch event business rule to go to the Business Rule page.
7. Select the Update, Delete, and Query check boxes.  
   Additionally, if you wish CI relation rollups to recalculate when there is a change to a relationship, use a similar procedure to select the Active check box on the cmdb_rel_ci synch event business rule.
