Considerations and Limitations for Actionable Relationship Center (Original ARC)
Here are some things to keep in mind when you implement Actionable Relationship Center (ARC).
Required Editions
| Available in: Lightning Experience |
| Available in: Professional, Enterprise, and Unlimited Editions |
General
There’s no limit to the number of relationship columns you can display in ARC.
ARC displays up to 10 related lists that have a configured compact layout.
ARC isn't available in the Salesforce mobile app.
Record cards only show the first two fields that appear on the associated record’s compact layout.
ARC cards show actions based on available actions in the record page layout.
Custom actions can be added to record previews, but not to record cards.
ARC supports the following screen resolutions for Internet Explorer 11:
- 1920 x 1080
- 1600 x 1200
- 1440 x 900
- 1366 x 768
ARC - Financial Services Cloud Component
The ARC - Financial Services Cloud component is used in the older version of ARC.
- This component isn’t available in Experience Cloud.
- This component isn’t extensible to packages.
When ARC - Financial Services Cloud is a stand-alone component on a page layout, the record preview border in ARC is the background color. When ARC - Financial Services Cloud is embedded in a tab component, the record preview border in ARC is white.
Lightning Web Components don’t support preview capability for Internet Explorer 11. See Get Started with Salesforce: Considerations for Microsoft Internet Explorer for more information.
- You can continue to use IE11 to access Lightning Experience until December 16, 2017.
- If you opt in to Extended Support for IE11, you can continue to use IE11 to access Lightning Experience until December 31, 2020.
- IE11 has significant performance issues in Lightning Experience.
- This change doesn’t impact Salesforce Classic.
Some objects have no Lightning Web Component compact layouts defined and, as a result, have no preview capability. For Lightning Web Components without preview capability, the record preview is a blank sidebar web component. See User Interface API Developer Guide: Supported Objects for more information.
The Notes & Attachment cards don’t have customizable compact layouts. These cards always display the Last Modified Date and File Type fields.
