Create automatic billing from Rental contract

Hi ,

Scenario : We created one Rental contract document say "ZRNT" and one billing type we created "ZRNB" . Now requirement is "We create Rental contract for a particular customer for 1 year and i mention through billing plan that when to generate the rental bill for that customer , say for example 27th of every month .

Every Month on 27th , User will create a billing document with reference to this Rental contract and will sent to customer ,

But my requirement is , Billing document has to generate automatically by the system on 27th of every Month . Is there any setting like billing document to generate by the system in the background based on the billing plan

Regards
