I am new to PMA module setup and managed to complete setup.
Created new contract and project and added billing rule on contract, also it appears on On account transactions. When I am trying create invoice proposal getting the error as "Project does not allow for invoice proposals to be created"
Could you pls check and advise if I am missing any setup in order to generate invoice?
On Account Transactions:
Generate Invoice proposal: Error message "Project does not allow for invoice proposals to be created"
