Invoice generation using Event / Work distribution rules for T&M Projects

Hello All,

We are trying to generate Invoicing using oracle standard Distribution rule(EVENT/WORK)

Per my understanding Invoicing can be generated only if the expenditures are marked as Revenue generated.

In this case since we use  manual events are used for generating  Revenue  hence Oracle system does not   mark any expenditures as Processed for Revenue Recognition. Hence the Distribution rule(EVENT/WORK) that is designated for generating Invoicing does not consider any of the expenditures for generating invoices.

is my understanding correct?

if yes then what is the purpose of this rule?

Is there ay way that we can make the invoicing work using the oracle provided standard distribution rule (Event/Work) ?
