ABAP code example for Function Module CONTROL_REGISTER_OBJ_CB

The ABAP code below is a full code listing to execute function module CONTROL_REGISTER_OBJ_CB 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_callback_id  
 
 TYPE I
.


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

DATA(ld_callback_prog) = 'some text here'.

DATA(ld_callback_form) = 'some text here'.

DATA(ld_is_system_callback) = 'some text here'.

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_h_control
 
 TYPE CNTL_HANDLE ,
ld_callback_id
 
 TYPE I ,
ld_callback_prog
 
 TYPE SY-REPID ,
ld_callback_form
 
 TYPE C ,
ld_is_system_callback
 
 TYPE C .


ld_h_control = 'some text here'.
ld_callback_prog = 'some text here'.
ld_callback_form = 'some text here'.
ld_is_system_callback = 'some text here'.
