Output ignored (requirement 107 not fulfilled)

Dear All,

We set up a new confirmation controll for purchase orders. In test (output of message AUFB) we receive the message is not processed and we have for this message type the following message (Analyse output):

AUFB 502 Output ignored (requirement 107 not fulfilled)

What is this routine 107 and what have we to do to resolve this problem?

Thank you for your help.

Best regards,

Thomas
