BW 3.1 Open Hub ExtractionEnhancement: Using Literal Filename &Path

Applies To:

SAP BW Open Hub Extraction

Article Summary

With the help of Open Hub, you can extract data from BW and save it to the application server or alocal drive. Currently, BW 3.1 standard functionality does not allow you to specify the filename orpath when you save. This article provides a step-by-step solution that enhances current BW OpenHub functionality and enables you to use custom filenames and paths.

Overview: How It Works

When a user initiates open hub extraction by creating an InfoSpoke, behind-the-scenes activityinvolves OO ABAP which is calling classes to determine each of the different components involved inmaking the open hub extraction possible. In particular, this enhancement will focus on two standardclasses: one used to determine file destination name and path and the other to control the userinterface of the InfoSpoke which will ultimately allow the user to enter his/her own filename and path.

To make this enhancement, we will perform three tasks:

Task 1: Create a custom class to handle the file management: naming and location(all code supplied; please download and unzip “zcl_rsb_file_literal_methods.zip” and store forupload). You can download the zip file here.

Task 2: Modify the methods of a standard class to point to our newly created class, which willmanage the files as we’ve specified.

Task 3: Enhance the user interface to allow for user customization.

Step by Step Instruction

Task 1: Steps for Creating a File Management Custom Class

1. Go to transaction “SE24”2. Create Object Type: “ZCL_RSB_FILE_LITERAL”3. Click the “Create” Button:

4. Enter a description & accept the creation screen defaults5. Click “Save”

6. Enter Package & Transport information7. Click the “Superclass” Button

8. Enter “CL_RSB_FILE_GENERAL”9. Enter the following properties:

Message Class: “RSBO” Type group/Object type: “RS”

“RSBO” “RSUDT”

10. Accept the remaining defaults11. Click the “Methods” tab

12. Place the cursor on Method: “IF_RSB_OPEN_HUB_TARGET~RECEIVE_DATA”13. Click the “Redefine” button

14. Highlight the existing commented code & follow the menu path:Utilities More Utilities Upload/Download Upload

15. Navigate to the previously unzipped folder and select the corresponding file name with thesame Method name.

16. Save and Activate the method.

17. Return to the “Methods” tab by using the green arrow back button and repeat steps 12through 16 for the remaining methods

IF_RSB_OPEN_HUB_TARGET~RECEIVE_DATA

IF_RSB_OPEN_HUB_TARGET~BEFORE_EXTRACTIONIF_RSB_OPEN_HUB_TARGET~AFTER_EXTRACTIONIF_RSB_OPEN_HUB_TARGET~REQUEST_ROLLBACKCHANGE_PARMSCONVERT_INT_TO_EXTGET_INFOSAVECHECKGENERATE_CONTROL_FILE_CSVGENERATE_CONTROL_FILE_ASCDETERMINE_FILENAME

18. Return to the “Methods” tab to customize the last method in your custom class19. Click the create “Constructor” button

20. Save the changes and click the “Code” button21. Repeat steps 14 through 16

Task 2: Steps for Modifying Methods of a Standard Class to Use the Newly Created FileManagement Class

(a) Method: CHANGE_PARMS

1. Go to transaction “SE24”2. Display Object Type: “CL_RSB_DEST”3. Click the “Display” button

4. Double click on the method: “CHANGE_PARMS”

5. Click the “Change” Button and provide an access key to make the change.

Access key required to make changes

6. Click the Insert button and insert the following language statements (for location,see the illustration):

* clear filepath when change between server vs. local file

clear l_s_vdest-path.

7. Place the cursor on line 27 and Click the “Replace” button

8. Click the Replace button to insert the following code (for location, see theillustration):

* replaced for open hub extraction literal filename/path

data: l_r_file_applsrv type ref to zcl_rsb_file_literal.

9. Save and activate the changes

Sample Code: CL_RSB_DEST

Method: GET_OBJECT_REF_INT1. Double click on the method: “GET_OBJECT_REF_INT”

2. Click the “Change” Button.3. Insert the following code in place indicated in the GET_OBJECT_REF_INT code sample:

* replaced for open hub extraction logical filename/path

data: l_r_file_applsrv type ref to zcl_rsb_file_literal.

4. Save and activate the changes.

Sample Code: GET_OBJECT_REF_INT

Task 3: Steps for Enhancing the User Interface Properties

(a) Modifying a Method from a Standard Class to Control the User Interface

1. Go to transaction “SE24”2. Display Object Type: “CL_RSB_SPOK_VIEW”

3. Double click on the method “SET_SCREEN_2001”

4. Click the “Change” button5. Click the “Delete” button and remove the following lines:

6. Follow the same steps to delete the corresponding “endif” statement

7. Place the cursor at the following example and click the “Replace” button

8. Insert the following code in the allocated space:

* replaced for open hub extraction literal filename/path

e_input = rsboh_c_on.

9. Save and activate the changes

Sample code: SET_SCREEN_2001
