LSMW Recording issue

I created an LSMW recording using t-code su10 to update user master records from Central User Administration (CUA). Specifically, adding roles to users in a child system. "Batch input Recording" is the method selected in this recording. There are only 3 fields to work with , the userid, system id and the role name. The objective is to add the designated role to a user in a child system. The recording saves the system id but never saves the role. There are no error messages but still the role is never added to the user master record.

Any ideas, what can be causing this problem?

I just want to mention this. When the transaction is in recording mode the system displays a cua message confirming that the system was added to the record. After I acknowledge the message by hitting the "ENTER" key the recording ends automatically.

If the tcode is run manually, after closing the pop up message window the main screen is redisplayed. At this point I have to click on the "SAVE" icon to save the added roles also.
