• Rollup information between Lookup relationships not previously possible without writing Apex Triggers
• Define rollups using standard UI declaratively, no coding required
• Define filter criteria on rollups for example Rollup Amount on Opportunity onto Account for Closed Won
• Supports Realtime, Scheduled and Developer API modes
• Open source, available in code and managed package form.
• Managed package has passed Salesforce Security Review and is Aloha enabled (does not consume app, tab limits)

Please refer to the blog posts below for more detailed information.

The tool has been feature in a number of blog entries as it has evolved...

• A Declarative Rollup Summary Tool for Force.com Lookup Relationships
• Account Hierarchy Rollups #ClicksNotCode
• New Release: Declarative Rollup Summary Tool Community Powered!
• New Release: Spring’14 Declarative Rollup Summary Tool
• New Tool : Declarative Rollups for Lookups!

There is also an early releaes video demonstration here...

• Check Existings Apex Tests. This tool dynamically deploys Apex Triggers and Apex tests, please make sure your Sandbox and Production org tests are all fully working before you attempt to use this tool. Otherwise usage of this tool will be blocked until you resolve such errors. If you have an org with triggers on the sObject that will contain the roll up result, installation into sandbox is VERY HIGHLY recommended so that after Lookup Rollup Summary records are added/enabled, you should rerun all testmethods to ensure nothing has broken as your before/after update triggers on the parent sObject will re-execute.
• Existing Tests on Parent Objects. This tool will update the indicated fields on your Parent objects when it senses activity on Child objects. Ensure an Apex Triggers you have written on your Parent objects are written with best practices around bulkification in mind. If in doubt be sure to perform significant testing.

• This tool uses SOQL Aggregate queries and is subject to platform limitations. This basically means...
• For each rollup, there is a maximum of 50,000 child relation records that can be summarised each time child record/s insert/update/delete operations are made (which may process several configured rollups). The rollup processes children to rollup by their parent record relationship and an optional further filter if provided. Meaning so long as this relationship does not result in more than 50,000 child records per parent parent record it will be successful. Take a look at the second blog post above which describes some new configuration settings to help calibrate the tool when running the Scheduled or Calculate jobs to help work within the 50,000 row limit.
• For performance reasons ensure the fields used are indexed (lookups are by default) and also any fields used in the filter criteria. This can be very important as without this, a full table scan will occur when the platform executes the SOQL and cause performance issues. For more information from Salesforce please see here and here.
• When using the Realtime mode, Formula fields as fields to aggregate are not supported (validation will be added in a future release to block this). To work around this, either switch to Scheduled mode or in Relatime mode use a Workflow Field Update to copy the formula field value to a physical field and reference that.
• While the tool can be installed and enabled directly in production, sandbox testing is still strongly recommended.
• Professional Edition is not supported, due to the Metadata API used by the tool not being available in this edition.

Please feel free to raise feedback and issues via the Github Issues page here.

You can install a packaged version of the tool into your production org (sandbox testing as always recommended). Check the limatations and known issues above first!

If you are a developer obtain the source code from this repository if you wish to develop it further and/or contribute to it. Click the button below to deploy the source code to your developer or sandbox org.

KNOWN INSTALL ISSUE Sometimes the Permission Set files will not deploy, based on org differences, such as features enabled. If you encounter this problem, Clone the repo manually and use your IDE or Ant script to deploy without the Permission Sets. I will be looking into fixing this issue in the future.
