Hi Santosh,
Check the STAT2 field entries you have in Table T529A. This is how SAP determines if an action is a status changing one and only allows one of these each day. If field STAT2 is blank, not a status change. Otherwise, a change. If a second status changing action is done, it will replace the first. Also, if action code/reason code combination is already there, it will overwrite.
