ABAP code example for Function Module PROLO_FUNCTION_CHECK

The ABAP code below is a full code listing to execute function module PROLO_FUNCTION_CHECK 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_fcode  
 
 TYPE TDP2-FCODE
,
ld_num_functions  
 
 TYPE STRING
.


DATA(ld_modify) = 'some text here'.

DATA(ld_ord_modus) = 'some text here'.
 

SELECT single SREG 
  FROM TDP1 
  INTO @DATA(ld_register).

 

SELECT single STYP 
  FROM TDP1 
  INTO @DATA(ld_styp).

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_fcode
 
 TYPE TDP2-FCODE ,
ld_modify
 
 TYPE STRING ,
ld_num_functions
 
 TYPE STRING ,
ld_ord_modus
 
 TYPE STRING ,
ld_register
 
 TYPE TDP1-SREG ,
ld_styp
 
 TYPE TDP1-STYP .


ld_modify = 'some text here'.
ld_ord_modus = 'some text here'.

SELECT single SREG 
  FROM TDP1 
  INTO ld_register.


SELECT single STYP 
  FROM TDP1 
  INTO ld_styp.
