PA Breakdown with Buckets and Scripted Mapping Showing 0%

[Singhdeep70]

I am trying to build a Performance Analytics indicator in ServiceNow to show Incident Aging using buckets and breakdowns.

This is my first time working with buckets, scripted mappings, and breakdown sources in PA, so I may be missing an important configuration step.

Current Goal:
I want to group active incidents into age ranges like:

• 0-2 Months

• 3-5 Months

• 6-8 Months

• 9+ Months

and display them using a breakdown on an automated PA indicator.

What is currently working:

• Indicator collection works correctly

• Scheduled collection job runs successfully

• Indicator scores are collecting correctly

• Parent score shows 109 active incidents

• Breakdown rows appear in the scoresheet

Problem:
The breakdown rows always show 0% / empty values even though the parent indicator score is collecting correctly.

Current Configuration:

1. Indicator

• Type: Automated

• Aggregate: Count

• Collect breakdown matrix: true

• Collect records: true

1. Indicator Source

• Facts table: Incident [incident]

• Condition: Active = true

1. Breakdown

• Automated breakdown

• Attached to indicator

1. Bucket Group
   Buckets configured as:

• 0-2 Months → 0 to 2.99

• 3-5 Months → 3 to 5.99

• 6-8 Months → 6 to 8.99

• 9+ Months → 9 to 9999

1. Breakdown Mapping
   Currently using scripted mapping.

Important Observation:

• Parent indicator score collects correctly

• Breakdown rows are visible

• But breakdown values remain empty / 0%

I also noticed confusion around:

• Breakdown Source using Bucket 
  vs

• Normal Incident table breakdown source

If possible, could someone please provide the complete step-by-step process from:

• Breakdown Source

• Bucket Group

• Breakdown Mapping

• Indicator

• Collection Job

• Aggregation
