Billing in CRM.

Hi Experts,

I created service order in CRM. Order is error free. When i release the order

I cloud not find any billing due list. Even i cannot see my order to release in

"CRM_SRVBIL - Release Service Processes for Billing ".

I activated billing in CRM.I created billing unit assigned to s.org.

Created billing type and assigned item cat for billing. Item cat is "D billing relevant"

Every thing seems perfect. But why systme is not generating billing due list.

Awaiting for your reply.

Thanks

John
