Non Revenue GL in Item Type AR Invoice

Hi,

I have a requirement to select a non-revenue GL for the items in AR Invoice.

The business scenario is that the user will raise AR Invoice on the client at fixed time durations / milestones; however some of the work will be rendered in future; hence he does not want to recognize the revenue in the current period. He wants to take it to Unearned Revenue A/c (under Liability drawer). Later he will transfer it to Revenue A/c by entering a JE.

I am able to select a non-revenue GL or a liability GL in Service Type AR Invoice.

But in Item Type AR Invoice, when I enable the G/L Account field from the Form Settings, it shows me a list of only the Revenue GLs.

I am using India localization and SAP B1 9.1 PL00.

Thanks.
