ABAP code example for Function Module ENQUEUE_READ





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

DATA:
ld_number  TYPE SY-TABIX ,
ld_subrc  TYPE SY-SUBRC ,

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_number  TYPE SY-TABIX ,
ld_gclient  TYPE SEQG3-GCLIENT ,
it_enq  TYPE STANDARD TABLE OF SEQG3 ,
wa_enq  LIKE LINE OF it_enq,
ld_subrc  TYPE SY-SUBRC ,
ld_gname  TYPE SEQG3-GNAME ,
ld_garg  TYPE SEQG3-GARG ,
ld_guname  TYPE SEQG3-GUNAME ,
ld_local  TYPE SY-CTYPE ,
ld_fast  TYPE SY-CTYPE ,
ld_gargnowc  TYPE SY-CTYPE .


ld_gclient = some text here

"populate fields of struture and append to itab
append wa_enq to it_enq.
