Accounting Flag for Invoices

Hi,

We have a requirement wherein we need to identify invoices which are accounted in payables modules (not necessarily posted to gl).

As, Invoices accounting can be done in 3 ways:

a. Create Accounting (Draft): I don't thiank it updates any flag in the backend tables

b. Create Accounting (Final): It creates accounting for thr invoice, but the entry is not posted in GL.

c. Create Accounting (Fianl Post): It creates accounting for the invoice and posts the same in GL.

We are basically looking for accounting flag for case b (above) as there can be time lag between accounting and posting to gl.
