Purchase Order Printing

Hi,

We are facing a problem in Purchase Order Printing. Purchase Order is saved and it is subjected to go for Release Strategy and Work flow. Even though the Purchase Order is not released and not completed the workflow, we are able to print the Purchase Order by selecting the Print Preview and by entering the Print option from the Standard Tool Bar in ME21N and ME22N Transactions.

We need Purchase Order Printing only when the Release Strategy and the Work flow is completed. Is there any configuration available in SPRO?

Thanks in advance.
