SAP ERP system is normally taken down for maintenance or release purpose at least 5 times a year. ERP release cutovers may some times take 72 hours downtime when partners messages not allowed to be interfaced. Partners cannot be asked to stop sending the messages during this downtime period. Average count of messages are around 10000 a day.
As the messages coming into PO cannot be stopped, how all these messages could be managed to stage in PO and send to ERP in controlled way once it is open to accept the interface messages?
Thanks advance.
