authorization object creation manual method

hi gurus

I have a requirement to create authorization objects for my project. The scenario is, we have a query which gives the profit center data on a weekly basis.the users for this report are the project management people. we have not created the project management hierarchy, but presently supposed to use a role as Project Management. We have a set of users for this Project Management role.

Now based on this scenario i am supposed to create the authorization objects.

can anybody suggest me the right step by step method for creating the authorization objects.

I would like to have steps as what i need to do in RSD1, in PFCF, in RSSM and in the BEx.

you answers will be rewarded accordingly

thanks in advance

regards
