1. You need to remove the old generated files(certreq, cred_v2, local.pse, srcert) from previous certificate request. To do this you can either rename these files or create a new folder and move these files into it.

2. Login to http://service.sap.com/saprouter-sncadd and click the “Apply now” button. From the list of SAProuters registered to your installation, choose the relevant “Distinguished Name”.

3. Generate the certificate Request. To do this go to your SAProuter server and run this command on the saprouter directory.

sapgenpse get_pse -v -r certreq -p local.pse “<Distinguished Name>”

Example:  sapgenpse get_pse -v -r certreq -p local.pse “CN=example, OU=0000123456, OU=SAProuter, O=SAP, C=DE”

You will be asked twice for a PIN here. Please choose a PIN and document it, you have to enter it identically both times. Then you will have to enter the same PIN every time you want to use this PSE.

4. Display the output file “certreq” and with copy&paste (including the BEGIN and END statement) insert the certificate request into the text area of the same form on the SAP Service Marketplace from which you copied the Distinguished Name.

5. In response you will receive the certificate signed by the CA in the Service Marketplace. Copy&paste the text to a new local file named “srcert”, which must be created in the same directory as the sapgenpse executable.

6. With this in turn you can install the certificate in your saprouter by calling: sapgenpse import_own_cert -c srcert -p local.pse

7. Now you will have to create the credentials for the SAProuter with the same program (if you omit -O <user_for_saprouter>, the credentials are created for the logged in user account).

sapgenpse seclogin -p local.pse -O <user_for _saprouter>

Note: The account of the service user should always be entered in full <domainname>\<username>

8. This will create a file called “cred_v2″ in the same directory as “local.pse”

9. To check if the certificate has been imported successfully, run the following command: sapgenpse get_my_name -v -n Issuer

The name of the Issuer should be: CN=SAProuter CA, OU=SAProuter, O=SAP, C=DE

SAP: BDC Upload Program Template

I recently created my own BDC upload template that enables user to choose the processing mode, the update mode and options for Default Size, Continue After Commit, and Not a Batch Input Session easily.

Another good thing with this program is a functionality to generate an excel file template. The image below shows the actual screenshot.

I modified the SAP standard program BDCRECX1 and saved it as ZBDCRECX1. I used this for my BDC upload program instead of the standard BDCRECX1 include. You may download the source code of ZBDCRECX1 on the link below. I also included a sample upload program utilizing the ZBDCRECX1 include.

Enjoy coding! :)

2. Now go to transaction SICF and activate the following:
/sap/public/bc/its/mimes
/sap/bc/gui/sap/its/webgui

3. Run transaction SIAC_PUBLISH_ALL_INTERNAL to publish internet services.

4. Now browse to http://<servername>:<icmport>/sap/bc/gui/sap/its/webgui/

As simple as that, you can now use SAP webgui.

SAP: Export ALV to Excel File

This tutorial will teach you how to export an ALV report to Microsoft Excel  file. This is intended for abap programmers who already have a knowledge in ALV reporting as I will not show here how to create an ALV.

Assuming you already have an ABAP program with ALV report, what you need to do is add a button or menu that will trigger the function that will export the ALV data to Excel file. but before that let’s start first with the declaration of types and variables that we’re going to use.

VARIABLE DECLARATION
 
TYPE-POOLS ole2.			 " we will use OLE objects
DATA: v_excel 	TYPE ole2_object,        " Excel object
      v_wrkbkl  TYPE ole2_object,        " list of workbooks
      v_wrkbk   TYPE ole2_object,        " workbook
      v_cell    TYPE ole2_object,        " cell
      v_font    TYPE ole2_object,        " font
      v_row	TYPE i.			 " row

Now we’re done with the variable declaration, let’s proceed to the main program. We will create 3 forms: One is for the preparation of the Excel file, second is for the data export from alv cells to excel cells, and third is for error handling.

The code below is for the preparation of excel application object.

EXPORT_TO_EXCEL
 
* it_main and wa_main is the tables used in your ALV
FORM export_to_excel TABLES p_it_main STRUCTURE wa_main.
 
* Create Excel object
  CREATE OBJECT v_excel 'EXCEL.APPLICATION'.
 
* Call Error_handler form
  PERFORM Error_Handler.
 
* Show excel window
  SET PROPERTY OF v_excel  'Visible' = 1.
 
* get list of workbooks, initially empty
  CALL METHOD OF v_excel 'Workbooks' = v_wrkbkl.
  PERFORM Error_Handler.
 
* add a new workbook to workbook list
  CALL METHOD OF v_wrkbkl 'Add' = v_wrkbk.
  PERFORM Error_Handler.
 
* export ALV column header to Excel
* PERFORM export_data USING rows columns boldfont value
  PERFORM export_data USING 1 1 1 'header_1'.
  PERFORM export_data USING 1 2 1 'header_2'.
  PERFORM export_data USING 1 3 1 'header_3'.
  PERFORM export_data USING 1 4 1 'header_4'.
  PERFORM export_data USING 1 5 1 'header_5'.
 
* Loop through ALV rows and fields and transfer data to Excel
  LOOP AT p_it_main INTO wa_main.
    v_row = sy-tabix + 1.
    PERFORM export_data USING v_row 1 0  wa_bill-field1.
    PERFORM export_data USING v_row 2 0  wa_bill-field2.
    PERFORM export_data USING v_row 3 0  wa_bill-field3.
    PERFORM export_data USING v_row 4 0  wa_bill-field4.
    PERFORM export_data USING v_row 5 0  wa_bill-field5.
  ENDLOOP.
  FREE OBJECT v_excel.
  PERFORM error_handler.
ENDFORM.

The next code is for the export_data form.

EXPORT_DATA
 
FORM export_data USING x y z val.
  CALL METHOD OF v_excel 'Cells' = v_cell
    exporting
    #1 = x
    #2 = y.
  PERFORM error_handler.
 
  SET PROPERTY OF v_cell 'Value' = val.
  PERFORM error_handler.
 
  GET PROPERTY OF v_cell 'Font' = v_font.
  PERFORM error_handler.
 
  SET PROPERTY OF v_font 'Bold' = z .
  PERFORM error_handler.
ENDFORM.

And for the code of error_handler form.

ERROR_HANDLER
 
FORM error_handler.
  IF sy-subrc  0.
    CALL METHOD OF v_excel 'QUIT'.
    FREE OBJECT v_excel.
    v_excel-handle = -1.
    MESSAGE: 'Failed to export to Excel.' TYPE 'E'.
  ENDIF.
ENDFORM.

Now that we’ve completed all the 3 forms, all you have to do now is call the export_to_excel form to initiate the export. In the example below, I call the export_to_excel form on user command ‘M_EXP’.

USER_COMMAND
 
FORM f_user_command USING p_ucomm LIKE sy-ucomm.
  CASE p_ucomm.
    WHEN 'M_EXP'.
      PERFORM export_to_excel TABLES it_main.
    WHEN 'CANCEL' OR 'BACK' OR 'EXIT'.
      LEAVE TO SCREEN 0.
  ENDCASE.
ENDFORM.

SAP: table JEST (Individual Object Status)

JEST table contains object status that is either system status or a user status. Field STAT corresponds to the Object Status. Field INACT identifies whether the status is currently active or inactive and field CHGNR is the change number that identifies the change documents for an object and is incremented serially.

TJ02 table contains the list of system status and description. All statuses in this table are internal. This means they are consistent across objects and clients. A single object can have multiple active system statuses and user statuses & inactive ones.

TJ30 table contains the list of user status and TJ30T contains their description.

You could use function module STATUS_READ read active object status and STATUS_OBJECT_READ to retrieve the status profile of an object number.
