While Apsona grids offer flexible, inline editing for Opportunity Products (OpportunityLineItems), they do not support real-time field prefill, such as automatically populating the Unit Price when a Pricebook Entry is selected, as seen in Salesforce’s native UI. Similarly, calculated fields like Total Price (Quantity × Unit Price) are not computed during data entry.
To replicate native-like behavior, you can implement the following Salesforce-side workarounds:
Record-Triggered Flow or Apex Trigger: Automatically populate UnitPrice based on the selected PricebookEntryId after record creation or update.
Formula Field for Total Price: Use a formula field on the Opportunity Product object to calculate total price post-save.
Grid Configuration Enhancements: Mark Unit Price as required, guide users with instructional column headers, and restrict PricebookEntryId choices with filters.
Although Apsona grids can't fully mimic native prefill functionality, combining them with Salesforce automation provides a reliable, user-friendly alternative.
