Hi Pavan,
The notes you indicated seems pretty old.
Did you have a look at this one?
2019259 - SWPC: Poor performance
I am not sure what is your issue. I would suggest to run some traces on the program indicated by your EWA.
You can also try to look for correction related to that program or the table.
You should use STAD (with table activated in ST03) or ST12.
Hope it helps.
Regards,
Adel
