Assigning Authorization Objects to Users:
 
# Go to the screen (RSECADMIN) , and click on assignment button under user tab: 


# Now we can assign the created Authorization Object to any user using this tool. 



# Adding the created Authorization Object (ZDWKJTEST) to the user ZNBITSRTS. I will be using the same user through out this blog for running any query so that it can use the restrictions which are applying using the Authorization Object.






# We can also assign the authorization to users through role/profile using the standard Authorization Object S_RS_AUTH:




# User with Authorization Object 0BI_ALL is having full access to data, and can overwrite any other Authorization Objects assignment to it. 


# Query on InfoProvider with Authorization Objects: Below is the test query in which I added the InfoObject for which we created the test Authorization Object (ZDWKJTEST).
