I am a SAP security person with some experience and need to mass update user profiles (SU01) with their default communication method. My research has led me to use one of these: LSMW, BDC and eCATT. I cannot use a developer for this and have to do it on my own. Which method will work best for this case?
I ran all t-codes. I am not terribly familiar with them but I don't have programming access and I need to update 2000 user IDs. It is just one field in SU01 that needs to be udpated (Default communication method needs to be RML).
If I use LSMW with BDC, dont' I need programming access?
