Data structure for User Roles and Profiles

Hi

I would like to extract data (simply using SE16) for user roles and profiles so that I can perform data analysis offline.

I have hit a block with table USR10 as I cannot download more than 255 chars of the AUTHS field and I can't find an AGR_ table that already parses the data for me.

I have the parsing rules and can do this offline - I can't get all the data.

I have searched for answers already and not found an answer. I have investigated whether there is a table that contains the parsed data and the 255 char limit in SE16.

Any steer would be greatly appreciated.

Thanks ... Don
