ABAP code example for Function Module MSS_DYNAMIC_PARAMETER_SWITCH

The ABAP code below is a full code listing to execute function module MSS_DYNAMIC_PARAMETER_SWITCH 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_rfcdest) = 'Check type of data required'.
 

SELECT single CON_NAME 
  FROM DBCON 
  INTO @DATA(ld_con_name).


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

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

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_rfcdest
 
 TYPE RFCDEST ,
ld_con_name
 
 TYPE DBCON-CON_NAME ,
ld_parameter_name
 
 TYPE MSSDYNPAR ,
ld_on_or_off
 
 TYPE BOOLEAN .


ld_rfcdest = 'Check type of data required'.

SELECT single CON_NAME 
  FROM DBCON 
  INTO ld_con_name.

ld_parameter_name = 'Check type of data required'.
ld_on_or_off = 'Check type of data required'.
