Hello Bhanu,
Table MHIS
Manual calls are bearing the Call numbers >= 90,000,000, whereas Scheduled calls are having Call numbers 1,2,3 and so on. So query the MHIS table like in picture1 below for Manual calls and like in picture2 for scheduled calls. (ABNUM is for call number).
Picture1 (Gives you Manual Calls)
Picture2 (Gives you Scheduled Calls)
Also see the my reply in this similar discussion Maintenance Plan_Call generation_Manual call_scheduled call
