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

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_y_num_records
 
 TYPE I ,
ld_xt_erch_key
 
 TYPE ISUAR_KEY_IERCH ,
ld_xt_ercho_key
 
 TYPE ISUAR_KEY_IERCHO .


ld_xt_erch_key = 'Check type of data required'.
ld_xt_ercho_key = 'Check type of data required'.
