ABAP code example for Function Module CNVCF_CCE_CHECKSUM

The ABAP code below is a full code listing to execute function module CNVCF_CCE_CHECKSUM 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_checksum  
 
 TYPE CNVC_CCE_CHECKSUM
.


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

DATA(ld_logic) = 'some text here'.

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

CALL FUNCTION 'CNVCF_CCE_CHECKSUM'
  EXPORTING
    data =                       ld_data
*   logic =                      ld_logic
*   last_checksum =              ld_last_checksum
  IMPORTING
    checksum =                   ld_checksum
  EXCEPTIONS
    NOT_IMPLEMENTED =            1

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_checksum
 
 TYPE CNVC_CCE_CHECKSUM ,
ld_data
 
 TYPE CNVC_TAB4096 ,
ld_logic
 
 TYPE STRING ,
ld_last_checksum
 
 TYPE CNVC_CCE_CHECKSUM .


ld_data = 'Check type of data required'.
ld_logic = 'some text here'.
ld_last_checksum = 'Check type of data required'.
