mass maintainence of roles

Hi!

due to the implementation of the new G/L we have to adjust lots of authorization roles ....

We have changes related to a high number of roles quite often.

We are using already derived roles....this is only helpful if you want to add new transactions - it does not help for new authorization-objects. Isnt it?

Any ideas on how to make a mass change?

Table MASSFUNC maybe, or is there already a mehtod existing.

thanks in advance.
