Hi,

To read data from application server you need to READ DATASET

OPEN DATASET <filename> IN TEXT MODE FOR INPUT

encoding DEFAULT.

DO.

READ DATASET <filename> INTO wa.

IF SY-SUBRC EQ 0.

APPEND wa TO itab.

ELSE.

EXIT.

ENDIF.

ENDDO.

CLOSE DATASET <filename>.

Cheers,

Aditya

You have to use FILE commands to read the data from file

You can try this FM

CV120_READ_FILE2TABLE

hi,

Hi,

If u want to read from Files from Applicatin Server U can go for

Open Data Set File for reading in text mode encoding default

This option enables u to read the file from Application Server & coming to Reading Header details into one internal table & Item detail into One Internal table

U can use

AT First

On change of

conditions to read

First you can download the excel file to internal table form by using TEXT_CONVERT_XLS_TO_SAP.Then use the below logic LOOP AT itab INTO watab.

if watab-col01 = 'H' OR watab-col01 = 'I' .

AT END OF col01.

IF watab-col01 EQ 'I'. "Counter reset for next document

ENDIF.

ENDAT.

Endif.

ENDLOOP.

if not contact your basis team they might have disabled the authorisation
