Authorisation Analysis in SRM

Hi All,

Does anyone know how you analyse authorisation errors that arise within the SRM system, within normal R/3 systems we would use transaction SU53 to analyse errors. We are currently in the process of implementing SRM and we are experiencing number of errors when using BBP transactions in the web browser, but I am unaware of how to analyse these from a role perspective, does anyone know how this is done.

Thanks

Simon
