How to get Current logged in user and the roles assigned to the user.

[former_member182534]

Hi Reader,

This blog gives us the steps you need to perform to get the current logged in user and the roles assigned to the user.

This is a very common requirement we use in Web Dynpro Java.

Say for example depending on the back-end role assigned to the user should be able to view some specific details and perform specific operation.

Procedure:

Step 1 : Add "com.sap.security.api.sda" in to the dependencies of the WebDynpro Java DC.

Step 2 : Use the following code:

try {

   String roleId, uniqueName, displayName = null;

   IUser currentUser = WDClientUser.getCurrentUser().getSAPUser(); //Code to get current user

   Iterator<String> rolesAssignedToUser = currentUser.getRoles(true);//Code to retrieve all the assigned roles

  

   while (rolesAssignedToUser.hasNext()) {

  

   roleId = rolesAssignedToUser.next();//Code to read the role id

  

   displayName = UMFactory.getRoleFactory().getRole(roleId).getDisplayName();//Code to get the display name

  

   } 

   } catch (WDUMException e1) {

   e1.printStackTrace();

   } catch (UMException e) {

   e.printStackTrace();

   }

Step 3 : Use the following imports for the above code.

import com.sap.security.api.IUser;

import com.sap.security.api.UMException;

import com.sap.security.api.UMFactory;

I just hope this small code helps all. this definitely helped me in my project.

Happy to help

Cheers
