R48121 (Invoice generation) unable to create record in F4822 for Service Work order

In Service Warranty management module, once Billing Workfile (R1775) is run for Service Work order, it creates BWF record in F4812. After running R48121 (Invoice generation) , system is unable to create record in F4822 (Invoice Summary) for Service Work order. Is it working as per standard functionality? Although, after create AR entries program (R48199), invoice gets created in Customer ledger record. I wanted to understand if P4805(Invoice Sequence/Summarization key setup) works for service work order and creates record in F4822 accordingly.
