ABAP code example for Function Module LC_GET_HDB

The ABAP code below is a full code listing to execute function module LC_GET_HDB including all data declarations. The code uses the latest in-line data DECLARATION SYNTAX but I have included an ABAP code snippet at the end to show how declarations would look using the original method of declaring data variables up front. This will allow you to compare and fully understand the new inline method. Please note some of the newer syntax such as the @DATA is not available until a later 4.70 service pack (SP8).

DATA:
ld_ev_hdb  
 
 TYPE SAP_BOOL
.


DATA(ld_iv_con_name) = 'Check type of data required'.
.

CALL FUNCTION 'LC_GET_HDB'
* EXPORTING
*   iv_con_name =                ld_iv_con_name
  IMPORTING
    ev_hdb =                     ld_ev_hdb

ABAP code to compare 7.40 inline data declaration with original syntax

The below ABAP code uses the older none in-line data declarations. This allows you to see the coding differences/benefits of the later inline syntax. It may also be useful if you are using an older version of SAP as some of the newer syntax above, such as the @DATA is not available until 4.70 EHP 8.

DATA:

ld_ev_hdb
 
 TYPE SAP_BOOL ,
ld_iv_con_name
 
 TYPE DBCON_NAME .


ld_iv_con_name = 'Check type of data required'.
