Currently I am doing Master Data Enhancement in the extraction at R/3 side.
I wrote User Exit for Master Data at EXIT_SAPLRSAP_O2.
I have added a field to my datasource. Now when i try to run the EXIT_SAPLRSAP_O2 to populate the field it asks for a parameter I_CHABASNM and I_UPDMODE.
I really not able to map what are these fields, which parameter I should pass to run the population.
Please help me out.
