ABAP code example for Function Module J_2GCUSTOMER_CHECK_AFM

The ABAP code below is a full code listing to execute function module J_2GCUSTOMER_CHECK_AFM 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_i_kna1) = 'Check type of data required'.

DATA(ld_i_check_only_new_afms) = '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_i_kna1
 
 TYPE KNA1 ,
ld_i_check_only_new_afms
 
 TYPE STRING ,
ld_i_duplicate_afm_action
 
 TYPE STRING ,
ld_i_default_option
 
 TYPE STRING .


ld_i_kna1 = 'Check type of data required'.
ld_i_check_only_new_afms = 'some text here'.
ld_i_duplicate_afm_action = 'some text here'.
ld_i_default_option = 'some text here'.
