A developer is extending Business Central to handle bulk import of vendor data. The import process reads a CSV file, validates each row, and inserts vendor records. The developer needs to ensure that if any row fails validation, the entire import is rolled back, but the user should see a list of all validation errors at the end. Which approach should the developer take?

Perform all validation first, collect errors, and if any errors exist, raise an error before inserting any records.

Use the ASSERTERROR function to validate each row and continue on error.

Insert all records and then use the ERROR function to roll back the transaction if any validation fails.

Use a try-catch block around each row insert and collect errors in a temporary table, then commit the valid rows.
