Business value

Allow AL developers to write AL code that returns more than one error. The feature can be used to simplify validation scenarios where users can be presented with a list of things to fix.

Feature details

To support collectable errors, the following features are now included in AL code:

  • New properties on the ErrorInfo data type so that a call to the Error method can state whether the error is collectable.
  • New method attribute called ErrorBehavior that lets the AL developer choose to collect and handle errors that have been classified as collectable.
  • New methods that let the AL developer handle errors collected in the current method scope.
