Transform the data of DataSource

Since ECC6 version, it is recommended to use the implementation of the BAdI RSU5_SAPI_BADI instead of the traditional USER EXIT (EXIT_SAPLRSAP_001 to 004).

In this tutorial we will focus on changing transactional data.
 

1.Implementing the BAdI ZC_RSU5_SAPI_BADI 

Click on 

Enter the BAdI's name.

Enter the BAdI's description.

Save 

Now, click on the 'Interface' and double-click the name of the class.

For now, the BAdI is created but is not active.

2.The class ZCL_IM_C_RSU5_SAPI_BADI

We will look at the first method and writing the dynamic call.

2.1.The method of instantiation IF_EX_RSU5_SAPI_BADI~DATA_TRANSFORM

This method of instanciation allows to build the dynamic call of the private methods.

Variable declaration to recovery the Datasrouce's name

DATA : l_method TYPE seocmpname.

The method's name always must begin by a letter, here we had the prefix 'M'

CONCATENATE 'M_' i_datasource INTO l_method.

We verify that the global table contains data.

CHECK c_t_data[] IS NOT INITIAL.

We verify that the called method exists for the class ' ZCL_IM_C_RSU5_SAPI_BADI '.

SELECT SINGLE cmpname
  FROM seocompo
  INTO l_method
  WHERE clsname =  'ZCL_IM_C_RSU5_SAPI_BADI'
    AND cmpname = l_method.

If the method exists

CHECK sy-subrc EQ 0.

We call the method with the standard parameters.

CALL METHOD (l_method)
  EXPORTING
    I_UPDMODE    = i_updmode
    I_T_SELECT   = i_t_select
    I_T_FIELDS   = i_t_fields
  CHANGING
    C_T_DATA     = c_t_data
    C_T_MESSAGES = c_t_messages.

Now we add our method, the one who will modify the data of our DataSource.

2.2.The private method M_DATASOURCE_NAME

Double-click on the name of the method to focus on the detail.

2.2.1.The private domain

Start to modify the 'Private Domain' to inform the parameters of the method.

class-methods M_DATASOURCE_NAME
  importing
    value(I_UPDMODE) type SBIWA_S_INTERFACE-UPDMODE
    value(I_T_SELECT) type SBIWA_T_SELECT
    value(I_T_FIELDS) type SBIWA_T_FIELDS
  changing
    !C_T_DATA type ANY TABLE
    !C_T_MESSAGES type RSU5_T_MESSAGES optional.

2.2.2.The code of the method

For the example, ' datasource_structure ' is the name of the structure generated during the creation of DataSource.

Variable declaration.

FIELD-SYMBOLS: <L_S_DATA> TYPE datasource_structure.

We copy the global table to our internal table.

L_T_DATA[] = C_T_DATA[].

(...) "Your specific selections

Then we curl on the internal table to update the data.

LOOP AT L_T_DATA ASSIGNING <L_S_DATA>.
...
ENDLOOP.

Finally we transfer the data in the global table.

C_T_DATA[] = L_T_DATA[].

Do not forget to CLEAR your tables and variables.

3.BAdI activation

Launch the SE19 transaction.

Click on 

Click on the activation button 

Your BAdI is active.
