Summary

This white paper explains in details how to enhance DataSources with the new featured BAdIRSU5_SAPI_BADI.

It is shown how to implement each enhancement on a separated method of the BABI class, making the codemore organized and clear, then in the formerly user exits EXIT_SAPLRSAP_00X.

Enhancing DataSources wi th BAdI RSU5_SAPI_BADI

As of SAP_BASIS 6.20 and PI_BASIS 2004_1 (R/3 Release 4.6C) is available a more efficient way toenhance SAP standard content, using Business Add-Ins (BAdIs) rather than user exits.

The technical name of this BAdI is RSU5_SAPI_BADI, detailed on the SAP Note 691154.

Each enhancement will be implemented in a separated method of the BABI class, then the code will be moreorganized and clear.

Below, I describe in details, how it can be done, just following a simple few steps.

Before we begin, there are some pre conditions, that must be filled:

SAP_BASIS 6.20 and PI_BASIS 2004_1 must be installed on your system.

The BADI-definition RSU5_SAPI_BADI (SE18) must exists in your system.

Once the pre conditions ware verified, its time to go.

I will assume that the process of creating and enhancing extraction structures of a given datasource is knowby the reader.

If you have doubts about the creation and enhancement of data sources, consult the documentation on SDN.

Implementing the BADI.

SAP make available the definition of the BADI, the implementation must be created for us, as follows:

On transact ion SE19

Type

Define a implementation name for you r class.

Click to confirm.

Click on to activate de implementation.

Result: You have created the implementation of the BADI, that will used to create the datasourceenhancements.

Click on the TAB

Click on the link

You go to the class builder

On the class builder click on the method name:

Then paste the follow ing code:

method IF_EX_RSU5_SAPI_BADI~DATA_TRANSFORM.

**********************************************************

* To implement an exit for a

* datasource create your own method by copying the

* method _TEMPLATE_DATASOURCE and rename it to the name

* of your datasource. In case you enhance a Business

* Content datasource skip the 0 at the beginning (e.g.

* Datasource 0FI_AR_3 -> Method FI_AR_3

* The method is then called by the Exit Framework

*********************************************************

CHECK c_t_data IS NOT INITIAL.

Create a new method and name it:_TEMPLATE_DATASOURCE.

Then click over the name of the new method and paste the following code:

method _TEMPLATE_DATASOURCE.

* Data Definition

* DATA: lth_vbak type hashed table of vbak

* with unique key vbeln,

* ls_vbak type vbak .

* FIELD-SYMBOLS: TYPE .

* Init

* Perform always a mass select into an internal table* SELECT * FROM VBAK INTO TABLE lth_vbak

* FOR ALL ENTRIES IN C_T_DATA

* WHERE VBELN = C_T_DATA_VBELN.

* map the data

* LOOP AT C_T_DATA ASSIGNING .

* READ TABLE lth_vbak into ls_vbak

* with table key vbeln = -vbeln.* if sy-subrc eq 0.

* -VKORG = ls_vbak-vkorg.

* !!! No MODIFY necessary as the field is changed immediatly in the

* internal table by using Field Symbols

* endif.

* ENDLOOP.

endmethod.

Define the properties of this method as static and public

At this point you have created the implementation class for the BADI RSU5_SAPI_BADI. That can be usedfor any extractor, standard or custom, to populate enhanced fields. And you have a template to build newenhancements for DataSources.

Result: You have created the methods needed to make enhancements of the datasources.


10/16



2007 SAP AG 10

Creating a enhancemente of a datasource.

I will assume that you have enhanced the structure of the data source, and need to code to populate theenhanced fields of the structure.

Copy the method _TEMPLATE_DATASOURCE and rename it, with the same name of the datasource youwant to enhance. In case of standard datasource, omit the first character of the name (0 or 2).

ie. DataSource 2LIS_18_IOTASKMethod name: LIS_18_IOTASK

ie.

Declare on the code the structure to populate.

On the code, you have to declare the structure of the type of the enhancement sctructure ofyour data source, ie:

Trans: RSA6

As you see in the picture, the Extract Structure of the data source 2LIS_18_I0TASK is MC18I00TSK.


11/16



2007 SAP AG 11

Declare:

FIELD-SYMBOLS: TYPE MC18I00TSK.

During the execution of the extraction process, when this method is called, the structure C_T_DATAwill bepopulated with packages of 100 records each time. So a loop must be declared to process these datapackages, as you see on the code examples bellow.

Bellow you have too examples of how to code your enhancement:

Here a simple way to populate the fields of the structure straight from the select:

method DS_FICA_VIEW_ZVDSFICACI.

FIELD-SYMBOLS: TYPE ZOXBND0152.

* map the data

LOOP AT C_T_DATA ASSIGNING .

SELECT SINGLE BETRH BETRW INTO (-BETRH, -BETRW)

FROM DFKKOP WHERE OPBEL = -OPBEL AND

OPUPW = -OPUPW AND

OPUPK = -OPUPK AND

OPUPZ = -OPUPZ.

ENDLOOP.

endmethod.

And here a slight more complex example, using some functions inside the code:

METHOD lis_18_i0task.

DATA: l_anw_stat_existing TYPE xfeld,

l_e_stsma TYPE jsto-stsma,l_line TYPE bsvx-sttxt,

l_user_line TYPE bsvx-sttxt,

l_stonr TYPE tj30-stonr.

*************************************************************************

* FIELD-SYMBOLS *

*************************************************************************

FIELD-SYMBOLS: TYPE MC18I00TSK .

*************************************************************************

* CONSTANTS *

*** The DataSource loads a package of 100 records each time, then

-ZSTSUSU = L_USER_LINE(4).

*** SEARCH THE STRING 'ANUL'

search l_user_line for 'ANUL'.

IF sy-subrc = 0.

-zflanu = 'ANUL'.

ENDIF.

ENDLOOP.

ENDMETHOD.

Go to the transaction RSA3 and test your data source.

Conclusion:

With this new method of creating enhancements, SAP makes available a more clear and effitient way toenhance datasources.

I hope this article be useful to help you to enhance standard, or develop this own datasources, using thisnew feature.
