Implement CL_ABAP_GZIP

Former Member — Wed, 28 Jun 2006 03:03:06 GMT

Hi,

I know this is not a new topic in this Forum but there is no node which shows how it is implemented. I need help on how to use this class to ZIP a file and output to Local Workstation. The source data is from a SAP table.

Anyone could help me on this?

Thank you.

hmm.. doesn't seems to be what I'm actually looking for. i have code some sample here


REPORT  ZCOMPRESS.

TABLES : VBAP.

DATA : BEGIN OF XTAB OCCURS 0,
         VBELN(10)   TYPE C,  SP01(1)  TYPE C,
         POSNR(10)   TYPE C,
       END OF XTAB.

*-- Here is the constant for TAB
CLASS CL_ABAP_CHAR_UTILITIES DEFINITION LOAD.
CONSTANTS: C_CON_TAB TYPE C VALUE
           CL_ABAP_CHAR_UTILITIES=>HORIZONTAL_TAB.

SELECT * FROM VBAP UP TO 1000000 ROWS.
  MOVE-CORRESPONDING VBAP TO XTAB.
  MOVE C_CON_TAB          TO XTAB-SP01.
  APPEND XTAB.  CLEAR : XTAB.
ENDSELECT.

*-- Download FM
*-- Here the file (Test-raw.txt) is the raw un-compress
*-- version

*-- I need to output it as a zip file ?

CALL FUNCTION 'GUI_DOWNLOAD'
  EXPORTING
    FILENAME                = 'D:TempTest-raw.txt'
    FILETYPE                = 'ASC'
  TABLES
    DATA_TAB                = XTAB
  EXCEPTIONS
    FILE_OPEN_ERROR         = 1
    FILE_READ_ERROR         = 2
    NO_BATCH                = 3
    GUI_REFUSE_FILETRANSFER = 4
    INVALID_TYPE            = 5
    NO_AUTHORITY            = 6
    UNKNOWN_ERROR           = 7
    BAD_DATA_FORMAT         = 8
    HEADER_NOT_ALLOWED      = 9
    SEPARATOR_NOT_ALLOWED   = 10
    HEADER_TOO_LONG         = 11
    UNKNOWN_DP_ERROR        = 12
    ACCESS_DENIED           = 13
    DP_OUT_OF_MEMORY        = 14
    DISK_FULL               = 15
    DP_TIMEOUT              = 16
    OTHERS                  = 17.

I need the downloaded file to be a compressed zip file. Any idea?

for the zip question you have an example in SDN:

- download area

- code sample

- Technologies

- ABAP code samples

The name of the document is:

<b>"Abap class to gzip and gunzip.pdf"</b>

as for the FTP have a look at sap standard program:

RSFTP002

if not u can check this link u may get some idea

EXPORTING

FILENAME = p_filename

CHANGING

DATA_TAB = p_table

EXCEPTIONS

FILE_WRITE_ERROR = 1

NO_BATCH = 2

GUI_REFUSE_FILETRANSFER = 3

INVALID_TYPE = 4

NO_AUTHORITY = 5

UNKNOWN_ERROR = 6

HEADER_NOT_ALLOWED = 7

SEPARATOR_NOT_ALLOWED = 8

FILESIZE_NOT_ALLOWED = 9

hi eddy,

Thanks for your effort here but I need to ZIP up the file before downloading it. The download function module is working fine but what I need is to implement the CL_ABAP_GZIP to zip the download file before downloading it.

thank you and regards;

wow... this guy is creating his own class for the zip function. not sure if i need to create this entire class to have the job done, but if yes then i have to study his coding 1 by 1. hmm... anyone who has done this kind of task before please help.

anyway thanks a lot kishan.
