Hello Andreas,
Thanks for the reply. It did help only thing i was missing is the flag to set on for minute based extraction. However it is happening only once in an hour and not less that that. Is this because of the setting for the parameter BWFINSAF. The default value of 3600 is there currently and i did not try to change it as the note says so.
Does this mean i cannot extract say for every 30 min?
