Declarative Rollups for Lookups!

Build Status

Features Summary

  • 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)
  • NEW Supports Custom Metadata, rollups can be included in Change Sets and Packages for easier deployment

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

Documentation

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

NOTE: The links are in chronological order, if your new to the tool, read from the bottom upwards

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

Implementation Considerations

  • Professional Edition. Professional Edition is supported only when using Process Builder or a Scheduled Full Recalculation. Ignore prompts to setup the Remote Site for Metadata API callouts, as this will not be needed. You can use either the new Manage Lookup Rollup Summaries tab (recommended) or the older Lookup Rollup Summaries tab. Make to select Calculation Mode as Process Builder when setting up your rollup (this will not require an Apex Trigger deployment). Please note that record deletion is not captured using Process Builder. For more information on using Process Builder with this tool see 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.

Usage Information and Known Issues

  • Platform SOQL Limits. This tool uses SOQL Aggregate queries and is subject to platform limitations. This basically means...
  • Deployment issues into Production. This tool dynamically deploys a small trigger and test class to the org. This is subject to the same rules and compliances as as a regular human developer. The generate test class, can in some cases be to simplisitc to get code coverage, requiring at present a developer to assist with the deployment, especially to production. There is more details on how to look for this scenario and how to workaround it, as well as future thoughts here.
  • Volume Considerations. 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 this blog post which describes some new configuration settings (see bottom of blog post) to help calibrate the tool when running the Scheduled or Calculate jobs to help work within the 50,000 row limit.
  • Indexing Fields. 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.
  • Realtime Mode and Formula Fields. 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.
  • Sandbox Testing. While the tool can be installed and enabled directly in production, sandbox testing is still strongly recommended.
  • INVALID_SESSION_ID: Invalid Session ID found in SessionHeader: Illegal Session faultcode=sf:INVALID_SESSION_ID faultactor=. This can occur when your using the Manage Child Trigger button or editing rollups via the Manage Lookup Rollup Summaries tab. Solution is to disable the 'Lock sessions to the IP address from which they they originated.' setting under Session Settings under Setup. Salesforce documentation notes the following 'This option can inhibit various applications and mobile devices.'. Note this issue only applies while configuration changes are being made with the tool, especially via the Manage Lookup Rollup Summaries (see release notes v2.0). Once rollups are configured this issue does not apply during rollup calculations.
  • Schedule Mode Setup. This is not so much a know issue, but a known source of confusion with the current tool. If you want to use the schedule mode features please read this first

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

IMPORTANT NOTE: This release improves the query optimisation within the tool when there are multiple rollups. There is also a small change in behaviour from previous releases, relating to default ordering. If you have been using concat, first or last operations and have not specified explicit order by on the rollup, you must do from now on, it no longer defaults to the field to rollup. In prior releases the behaviour of this operation may or may not have been consistantly working as expected, depending on the existance of one or more rollups.

Installing the Source Code (Developers)

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.

Deploy to Salesforce

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.
