Runtime decision for FM ?

[Former Member]

How can i make my report decide which method to use for file upload based on : whether it is run in foreground or background at run time ?

I tried using the sy-batch system variable like this :

if sy-batch = 0.

OPEN DATASET fname FOR INPUT IN TEXT MODE ENCODING DEFAULT.

WHILE SY-SUBRC = 0.

READ DATASET fname INTO i_holdT.

IF SY-SUBRC = 0.

append i_holdT TO I_HOLD.

ENDIF.

ENDWHILE.

CLOSE DATASET fname.

else.

call function 'GUI_UPLOAD'

exporting

filename = fname

• filetype = 'ASC'

• HAS_FIELD_SEPARATOR = ' '

• header_length = 0

• read_by_line = 'X'

• DAT_MODE = ' '

• CODEPAGE = ' '

• IGNORE_CERR = ABAP_TRUE

• replacement = '#'

• CHECK_BOM = ' '

• VIRUS_SCAN_PROFILE =

• IMPORTING

• FILELENGTH =

• HEADER =

tables

data_tab = i_hold

• 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

.

if sy-subrc <> 0.

• MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

• WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

endif.

endif.

But when i debug the code , while running in forground , the sy-batch has nothing in it ...!! and when run it in foreground it throws an exception of " CONV_NO_NUM".

If anyone has sample code or idea how to ahcieve this , pls help !

Thanks

Hi,

You should check SY-BATCH = 'X' for background..and not SY-BATCH = 0..

Thanks,

The valid values for Sy-batch are X and space.

sy-batch = 'X' mean running in background and space means foreground.
