The IDoc processing Sequence
Our SAP ECC 6.0 system receives IDocs of different message types from a XI system, let's say the message types are: MSG_1, MSG_2, MSG_3. The three message types must be processed in such order, otherwise error may happen.
The current problem is that sometimes the processing of MSG_1 is not successful, but the system is still continuously receiving and processing messages from XI, so the subsequent MSG_2 and MSG_3 are also not processed successfully.
So my question is how to make the system stop processing certain type of message if its predecessor is in error status.
