Forum Post: RE: How to create a error message on post action of journal voucher(16571) if line narration and voucher narration are empty

Hi, You need to create a function and check for all lines having records in "Gen. Journal Narration" Table or not. Give it a try and let us know what you tired. Tip - ** Primary key of "Gen. Journal Line" is a part of key of "Gen. Journal Narration" and try to zoom the voucher narration record and see how you can link them..
