Sources for Exceptions When You Save Data into a Batch

When you save data into a batch table through the batch grid user interface, exceptions may arise from many sources:

• Form Field Metadata

• Database Constraints

• RaiseError() within Save Implementations

• Batch Event Handlers

Without some background, it can be hard to decipher where errors originate. So let's explore some of the ways that you can cause exceptions when you save rows to a batch.

<TextField Name="NAME" Length="100" Required="true" />
