Hello Rinaz,
Can you check a message in status 14 in SXMB_MONI, take the message ID and search for this message in SXMSPMAST2, using transaction SE16. Can you then detail the ITFACTION and REORG values for this message.
When using Test and Log options in report RSXMB_CANCEL_MESSAGES are any messages flagged?
Regards
Eoin
