Suggestion:

• Create sales invoice lines as a list
• Include deferral code to table options for the list

I would like to filter sales invoice lines by deferral code to control correct application of deferral code before posting

I can filter on deferral code on posted sales invoice lines, but at this stage the journal is already posted and if deferral code has been applied incorrectly, I'll have to reverse journal.

Thx in advance
