List views rendered with Lightning Web Components (LWC) now prevent you from selecting or attempting to edit more than the supported maximum of 200 records at one time. Previously, if you selected more than 200 records, the edit icon still appeared and Salesforce didn’t restrict you from changing a field. However, when you attempted to apply your changes, an error notified you that your changes were unsaveable. To save you time and prevent the input of changes that can’t be saved, list views now enforce the 200-record limit earlier in the edit process.
Where: This change applies to Lightning Experience in all editions.
