ME28 Cancel release of purchase order


when I try to perform a cancellation of a release of a PO I get an error message:

ME 175 Document already treated. Function not possible

It should be possible to cancel the release of alll released purchase orders. Can you help me?

Thanks a lot!

    please read the following:

    Note 493900 /12. Question :

    Is it possible to cancel a release strategy when the purchase order has

    been printed out ?

    Answer :

    With ME29N you cannot cancel a release strategy once the document has

    been printed out. This behaviour constitutes a new design. Regarding

    ME28 it has been decided to keep the old behaviour and you can cancel

    the release if there is at least one message type which has not been

    printed out.

    Please note AT LEAST ONE message type has NOT been printed out with


    Alternatively, you can try the following:

    - Transaction: SPRO

    ->MM->Purchasing->PO->Release procedure for PO

    ->Define relesae procedure for PO

    ->Release Strategies

    ->Release Status

    - choose the button release indicator and

    5 Changeable, new release if new strategy/outputted

    6 Changeable, new rel. if new strat. or value change/outputted

    - go into transaction ME22(N)

    - you will get the warning message 06 684 stating

    'Releases already effected are liable to be reset'

    - change the price and save the p.o.. Now a change message will be

    created and will be send to the vendor again.

    - Please note that the release strategy will only be reset if the price

    is increased. When it is decreased it won't be reset. But in both

    cases a change message will be created and send to the vendor.

    - after the change of the p.o. you will have to release it again. After

    the release the change message will be printed.

    Hope this will help to solve the issue,

    Please check the Purchase order history in ME23N as as per the error MIGO is done for this line item or Order.

      Thanks for your answer but MIGO was not done yet. It is directly after performing the ME28 release that I try to cancel it and that the error is there
