Thanks Stephen for the link. I dived into the content , Prepared Course Program with Blocks/Sequentially and non sequentially.
When I subscribed the course program created using T-Code : LSO_SUBSCRIBE_CP, it shows an error "Enter a valid participant" . For this I maintained T777BIRTH Table with P 25 E . Not able to subscribe still.
Did I miss anything?
