# Review the breakdown sources

# Review the breakdown sources {#ariaid-title1}

Breakdown sources represent the elements that you use to examine a KPI in more
detail. Modify the breakdown source to limit the element list to only those items that are
meaningful for the data analysis.

## Before you begin

Role required: pa_admin, admin

## About this task

For example, the Assignment Group automated breakdown uses
the Groups breakdown source. This breakdown source returns ALL active groups in your
instance, and the system uses all these groups to examine your data. If you look at the
Number of Open Changes indicator, and you examine the Assignment Group breakdown, you
see all groups in your instance instead of just the groups that are actually working on
your Change requests.  
Restricting the number of elements that a breakdown source returns has the following benefits:

* Smaller element lists make it easier for consumers to find the data they need. Sorting through a list of 25 groups associated with a particular process is easier than trying to sort through thousands of groups.
* Smaller element lists lead to less data collection and more efficient use of data. Instead of the [data collector](https://servicenow-prod.fluidtopics.net/KzO1fGsm6GUEygdn1yjLBA#gloss-data-collector "A scheduled job that collects data from one or more indicator sources to produce indicator scores.") crunching through 1,000 different groups, the data collector can analyze the 25 groups that are meaningful to the process.

Note:  
You probably do not need to change the breakdown sources in Platform Analytics Solutions. However, you may find it helpful to review and understand exactly what is being measured in your processes.

## Procedure

1. Navigate to AllPerformance AnalyticsSourcesBreakdown Sources.
2. Click a breakdown source to see its details.
3. In the Source tab, examine the definition for the breakdown elements, including the table that contains the unique list of sys_ids.  
   For example, in the Change.Impact breakdown source, the unique values contained in the Change Request Impact field come from the Choice \[sys_choice\] table. The conditions provide additional filters to ensure that the query returns only the Change Impact fields from the Choice \[sys_choice\] table.
4. Click Preview to see the number of elements that the query returns.  
   In the example, the query returns three impact elements.

5. Click x records match condition to see the specific values that the query returned.  
   In the example, clicking 3 records match condition opens a new browser tab with a filtered list of records from the Choice \[sys_choice\] table.
6. Verify that the list of records match what you expect to see in the breakdown element list.
7. If the records were not what you expected, modify the conditions in the Source tab of the breakdown source to match your environment and repeat steps 4-6 until you are satisfied.
8. Click Update to save your changes.

## What to do next

You are now ready to collect data, as described in [Collect data for Platform Analytics Solutions](https://servicenow-prod.fluidtopics.net/lW1zzQ5x853hHB3jU~tOOQ "After you install an Platform Analytics Solution and ensure that it points at the correct data structures in your instance, collect the data for the indicators and breakdowns.").
**Previous topic:** [Update Performance Analytics scripts](https://servicenow-prod.fluidtopics.net/g2ohrzxvaFIjje~68c_FzA "Platform Analytics Solutions include Performance Analytics scripts to perform calculations on records. These scripts use the time stamp fields from the indicator sources. If you change the time field stamps in an indicator source, also modify the related scripts.")  
**Next topic:** [Collect data for Platform Analytics Solutions](https://servicenow-prod.fluidtopics.net/lW1zzQ5x853hHB3jU~tOOQ "After you install an Platform Analytics Solution and ensure that it points at the correct data structures in your instance, collect the data for the indicators and breakdowns.")
