Control Billing on a Multi-Customer project funded at project level

Hi All,

We have a contract project (DL: Work/Work) with 2 customers with 25% and 75% contribution, which were funded at project level by 2 agreements (1 for each customer). When we generate an invoice/revenue, system is generating 1 invoice/revenue for each customer with prorated amounts.

Now, we want to stop billing one of the customers temporarily and bill the other customer.

Please advise how we can fulfill this requirement.

Thanks in advance.
