When the Application field is required in an ERB, you might notice that you get an exception when trying to validate the batch for the first time. If the Application field has a default value, the exception will be blank. If the Application field has no default value, the exception will state, "Required field missing: Application" even if it is selected.
There are two workarounds: Validating the batch a second time will clear the exception. The other option is to edit the batch template and change the field so that it is no longer required.
We are currently evaluating this issue for a fix in a future service pack.
