BW 3.1 Open Hub Extraction Enhancement: Using Literal Filename & Path

Transcription

1 BW 3.1 Open Hub Extraction Enhancement: 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 a local drive. Currently, BW 3.1 standard functionality does not allow you to specify the filename or path when you save. This article provides a step-by-step solution that enhances current BW Open Hub functionality and enables you to use custom filenames and paths.

2 Overview: How It Works When a user initiates open hub extraction by creating an InfoSpoke, behind-the-scenes activity involves OO ABAP which is calling classes to determine each of the different components involved in making the open hub extraction possible. In particular, this enhancement will focus on two standard classes: one used to determine file destination name and path and the other to control the user interface 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 for upload). You can download the zip file here. Task 2: Modify the methods of a standard class to point to our newly created class, which will manage 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 defaults 5. Click Save

3 6. Enter Package & Transport information 7. 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 defaults 11. 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

4 15. Navigate to the previously unzipped folder and select the corresponding file name with the same Method name. 16. Save and Activate the method. 17. Return to the Methods tab by using the green arrow back button and repeat steps 12 through 16 for the remaining methods IF_RSB_OPEN_HUB_TARGET~RECEIVE_DATA IF_RSB_OPEN_HUB_TARGET~BEFORE_EXTRACTION IF_RSB_OPEN_HUB_TARGET~AFTER_EXTRACTION IF_RSB_OPEN_HUB_TARGET~REQUEST_ROLLBACK CHANGE_PARMS CONVERT_INT_TO_EXT GET_INFO SAVE CHECK GENERATE_CONTROL_FILE_CSV GENERATE_CONTROL_FILE_ASC DETERMINE_FILENAME 18. Return to the Methods tab to customize the last method in your custom class 19. Click the create Constructor button 20. Save the changes and click the Code button 21. Repeat steps 14 through 16

5 Task 2: Steps for Modifying Methods of a Standard Class to Use the Newly Created File Management 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 the illustration): * replaced for open hub extraction literal filename/path

6 data: l_r_file_applsrv type ref to zcl_rsb_file_literal. 9. Save and activate the changes Sample Code: CL_RSB_DEST

7 Method: GET_OBJECT_REF_INT 1. 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.

8 Sample Code: GET_OBJECT_REF_INT

9 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_ Click the Change button 5. 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

10 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

11 (b) Modifying Screen Attributes 1 Create a Domain 1.1 Go to Transaction SE Select the Domain radio button 1.3 Enter RSPATH 1.4 Click the copy button 1.5 Enter the Copy To field 1.6 Select the Definition tab 1.7 Set the Lowercase option by clicking the Lowercase checkbox 1.8 Save and activate

12 2 Create a Data type 2.1 Go to Transaction SE Select the Data type radio button 2.3 Enter RSBPATH 2.4 Click the copy button 2.5 Enter the Copy To field 2.6 Select the Data Type tab 2.7 Enter the newly created domain 2.8 Save and activate

13 3 Assign the custom Component type 3.1 Go to Transaction SE Select the Data type radio button 3.3 Enter RSBODYN Click the change button Access key required to make changes 3.5 Enter the newly created data element in the component type for component: PATH 3.6 Save and activate 3.7 Confirm screen properties changes Go to transaction SE Enter RSBO_GUI under function group

14 3.7.3 Expand screens and double click on screen Click the Element list tab Click the Special attr. Tab Scroll down to RSBODYN2001-PATH type I/O Confirm that Upper/Lower case entry is checked (If setting not applied, screen properties may need to be re-activated - access key would be needed for R3TR FUGR RSBO_GUI )

15 3.8 Turn off upper case formatting on file path when using search help While still in screen 2001, Go to the Flow Logic tab Double click on module f4_path_ Double click on method f4_path Double click on method dynp_values_read_2001

16 3.8.5 Use the replace button to replace the exporting parameter rs_c_true with rs_c_false in the call function DYNP_VALUES_READ in order to turn off the upper case option
