Multiple Sales Order Invoicing Againt One Invoice in Project Module

Greetings Team,

I am facing a challenge while invoicing multiple sales orders through invoice proposal in project module.

Case study - I have created a project ABC001, type - Time & Material. I have created 3 sales orders on the same date against this project and used invoice proposal functionaity to invoice these 3 sales orders. However system takes all the 3 sales order lines into one invoice and post it which doesn’t seem a practical situation. In this case all the sales orders will be having same invoice number and tracking will be difficult. Tracking becomes more difficult if some of the orders are partial invoicing.

Moreover in a practical scenario, it is not necessary that customer will accept one invoice against multiple sales orders.

Could you please let me know if there is a parameter setting I am missing since I want to invoice sales order seperately instead of at summary level.
