Generate Lease Accounting Prepayment Invoices and Revenue Recognition with Tax Requirement

Good day,

Users have a legal requirement to report tax to the tax authority when one of the following comes first, Customer bill, Customer advance, or revenue recognition.

with the new implementation we have all the mentioned cases can happen, but they cannot generate a customer advance (prepayment) from the source lease accounting to apply it to the standard invoice when generated.

Users also have a case where revenue is recognized before billing (billing in arrears) and they cannot calculate tax with revenue recognition?

would appreciate a solution or a workaround if any for the above cases as it crucial for the ongoing implementation and go live activities.
