ARE1 exports under LOUT

Hi ,

While we create a ARE1 w.ref to a Export invoice under letter of undertaking system gives an error message " EXPORT UNDER BOND SPECIFY A BOND NUMBER AND YEAR ".

But the export type determined in the ARE1 form is " Export under LOUT " as selected in Excise invoice still this problem is avoiding us to create ARE1 .

Please help.

Thank you
