Hi Shalini,
Go to RSANWB T-code and select any analysis process. Then press the "monitor" button. On the monitor screen, you can see the selection criteria in a table on the right. Now double-click on the table and a popup will come up where you can set the selection criteria. in particular, you can set the time frame and the analysis process selection.
Hope it 'll help you..........
Regards,
Mukesh
