How to Create and Use the Authorization Objects in ABAP

Published by rson.

Authorization Objects are used to manipulate the current user’s privileges for specific data selection and activities from within a program.

We could always create our own authorization objects and implement it in our own abap programs. As an example, we will create our own authorization field similar to TCD used in S_TCODE Authorization object

Steps to create authorization field
1. Go to transaction code SU20
2. Click the create new button on the application toolbar.
3. Enter “ZTCODE” in the Field Name and “TCODE” in the Data Element, then hit Enter.
4. Click the save button on the system toolbar.

Steps to create authorization class
1. Go to transaction code SU21
2. Click on the Create button’s drop down icon and select “Object Class”.
3. Enter “ZTRN” on the Object Class field.
4. Give it a description and save it.

Steps to create authorization object
1. Again in SU21, in the list of authorization class(folder icon), click the one that we’ve created(ZTRN).
2. Click on the Create buttodrop down, this time selecting “Authorization Object”.
3. Enter “Z_TCODE” on the Object field and give it a description.
4. On the authorization fields section, enter ACTVT and ZTCODE. ACTVT is used to set and limit the activity of the user, while the ZTCODE is the authorization field that we’ve created earlier which is
responsible for holding a list of tcodes.
5. On the Further Authorization Object Settings, click on “Permitted activities” button. Here we will select the specific activities that we want to be available for our authorization object.
6. As an example, we will select 01(Create), 02(Change), and 03(Display).
7. Save and Exit.

Now we’re done creating our own authorization object, let us now use and assign it to a user.

Steps to create a role
1. Go to transaction code PFCG.
2. Enter “ZAUTHTEST” on Role field and click the “Single Role” button.
3. Now give it a description, click the save button and click the Authorization tab.
4. Click the “Change Authorization Data” button inside the authorization tab.
5. Then click the “Manually” button on the application toolbar and type in the name of the authorization object that we’ve created earlier(”Z_TCODE”) and press enter.
6. Expand all the nodes, double click on the input field of the Activity and select activity 01 and 02.
7. Enter the tcode of our own abap program in ZTCODE field, in our example I used “ZCOMM” .
8. And also don’t forget to add the S_TCODE authorization object and enter ZCOMM on it’s field.
9. Now Click on the Generate button in the application toolbar and press enter on the pop-up screen.
10. press the back button and assign a specific user on the user tab and click User Comparison button.
11. Now create another role by repeating steps 1 to 9 but this time select activity 03 on step 6.
12. Then assign this 2nd role to another user.

Now let’s implement this authorization in our ABAP program. Let say we have a dialog program(ZCOMM) wherein we have a button on the screen that when clicked, the user will go to the Create/Edit screen(1000) if he’s authorized. On the other hand, he will go to display only screen(2000) if he’s not authorized. To do that, simply add the code below on your program.

  AUTHORITY-CHECK OBJECT 'Z_TCODE' "authorization object that we’ve created
      ID ‘ACTVT’ FIELD '01'            "Activity = 01, authorized to create
      ID ‘ZTCODE’ FIELD 'ZCOMM'. "tcodes that we wants to check for authorization
  IF sy-subrc EQ 0.
      CALL SCREEN 1000. "The user is authorized to create
      CALL SCREEN 2000. "User is not authorized to create (Display only)
