ME29N Error when reset release strategy if the document is already printed

Hi Everyboby,

I try to reset the release strategy on my PO, but when click on reset release the following message appears :

ME175 : "Document has already been outputted (function not possible)"

So, how can I resolve this message?

I would like to condition the release cancellation according to the Purch. organization and release group.

Is there an UE that could be implemented?

I find the following UE : "EXIT_SAPLEBND_002" but the message appears before

I try to use the BAPI : "BAPI_PO_RESET_RELEASE" but the following message appears also because my document are already printed.

Can someone help me ?

Thanks in advance
