ABAP code example for Function Module MDMA_SINGLE_READ

The ABAP code below is a full code listing to execute function module MDMA_SINGLE_READ 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).

SELECT single MATNR 
  FROM MDMA

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_wmdma
 
 TYPE MDMA ,
ld_kzrfb
 
 TYPE MTCOM-KZRFB ,
ld_maxtz
 
 TYPE MTCOM-MAXTZ ,
ld_matnr
 
 TYPE MDMA-MATNR ,
ld_berid
 
 TYPE MDMA-BERID .



ld_kzrfb = some text here

ld_maxtz = 123 

SELECT single MATNR 
  FROM MDMA 
  INTO ld_matnr.


SELECT single BERID 
  FROM MDMA 
  INTO ld_berid.
