Cost Center Authorization

Dear Friends / Experts

We have around 10 HR (BW/BO) reports. All are woking fine. Now the users wants to restrict the report based on cost center.

Hence, I have created one DSO with relevent information and extracted the data from ECC ( Used id, Cost Center belonging, Etc....). Created one customer exit variable and lookedup this used cost center data in CMOD. This is perfectly working.

My Doubts

1) This logic no where related with authorization. Do i still need to consider authorization object and handle further ?

2) If the Logged in user not available in the DSO, i am not able to edit the query in BO-Webi .

Can anybody advise ?. Good advise awarded with points.

Regards
