Insert Custom Header in .CSV file generated in application server without creating any Temporary file in AL11.

Hi,

I was working on a requirement where I need to create a CSV file using APD in application server and insert a custom header.

The header insertion can be achieved using a ABAP program, also I found documents in SDN to achieve the same.

The issue with available logic in SDN is we need to create a separate temporary file in application server and then only we can insert the custom header.

Using below code we can insert the custom header without creating a temporary file in application server.

*&———————————————————————*

*& Report ZBW_INSERT_CUSTOM_HEADER

*&

*&———————————————————————*

*&

*& To insert a custom header into a CSV file generated by Analysis Process Designer in application server.

*&

*&

*&———————————————————————*

REPORT ZBW_INSERT_CUSTOM_HEADER.

*If file is LOGICAL

DATA: logical_file(60) type c VALUE ‘ZBW_LOGICAL_FILE’,    // Give logical file name.

file(60) TYPE C ,

result TYPE string,

temp TABLE TYPE string.

*If file is physical saved in local system

DATA: file(60) type c VALUE ‘c:\user\desktop\file.csv’,     // Give path of local desktop file.

result TYPE string,

temp TABLE TYPE string.

* Convert logical path and file name into physical path and file name

* Get physical file names

CALL FUNCTION ‘FILE_GET_NAME’

   EXPORTING

     logical_filename = logical_file

   IMPORTING

     file_name        = file.

OPEN DATASET file FOR INPUT IN TEXT MODE

ENCODING DEFAULT

WITH SMART LINEFEED.

* Read logical file data into temporary table.

CLEAR temp.

DO.

   READ DATASET file INTO result.

   IF sy–subrc = 0.

     APPEND result TO temp.

   ELSE.

     EXIT.

   ENDIF.

ENDDO.

CLOSE DATASET file.

DELETE DATASET file.

OPEN DATASET file FOR APPENDING IN TEXT MODE

ENCODING DEFAULT

WITH SMART LINEFEED.

* Insert custom header to logical file

SET DATASET file POSITION 0.

TRANSFER `cost centre;cost centre description;posting period;posting year;keyfigure1;keyfigure2;` TO file.

CLOSE DATASET file.

OPEN DATASET file FOR APPENDING IN TEXT MODE

ENCODING DEFAULT

WITH SMART LINEFEED.

* Transfer Temporary file data to Logical file.

DO.

   READ TABLE temp INTO result INDEX 1.

   IF sy–subrc = 0.

     TRANSFER result TO file.

     DELETE temp INDEX 1.

   ELSE.

     EXIT.

   ENDIF.

ENDDO.

CLOSE DATASET file.

Please note to include this program in process chain after APD execution.
