Accrual For the Purchase order

Hi All

for my non Stocked item i want to generate the accrual entry on product receipt, i make the check mark on the Model group but it is not effecting, here is the screenshot i have attached.

Please suggest how can i achieve it.

thanks in advance

Any Comments experts

The item must be stocked, if it is not then no accrual can take place as the service is considered consumed immediately and therefore they is no considered time lag for invoice (probably some logic like that, but I believe it has to be stocked to enable the accrual to work).
