You need to rebuild the indexes of tables related to SXMB_Moni
SXMSPMAST - master table
SXMSPEMAS
SXMSCLUR
and SXMSCLUP
This has solved my problem.
Please check and do the following:
.For rebuilding Please go to DB02 go to detailed analysis fill the Object Name & execute it,now click on Table Index,Select the Appropriate index,then go to detailed analysis,Now check the storage Quality of Index.Ideally it should be more than 75%.If the storage quality is quite less then go to index menu & rebuild Index.next day you will not get any warning related to this Index
