Hi Anupma,

Check this link

A sample code of how to use performs in sap scripts.

In script program,

/:PERFORM GET_SBGRP_STEXT IN PROGRAM ZSDSCRIPT
/:USING &GV_MATNR&
/:CHANGING &GV_STEXT&
/:TABLES INPUT_TABLE
/: OUTPUT_TABLE
/:ENDPERFORM


In program ZSDSCRIPT,

form get_sbgrp_stext tables intab structure itcsy
outab structure itcsy.

DATA: LV_MATNR LIKE MARA-MATNR,
LV_TEXT(3) TYPE C VALUE 'ABC'.
clear intab.
read table intab with key name = 'GV_MATNR'.
if sy-subrc = 0.
lv_MATNR = intab-value.
ENDIF.

CLEAR OUTTAB.
READ TABLE OUTAB WITH KEY NAME = 'GV_STEXT'.
IF SY-SUBRC = 0.
OUTAB-VALUE = LV_TEXT.
modify outab index sy-tabix.
ENDIF.

Cheers

check this link about FORM and PERFORM.

about DEFINE.

lets say your intension is to go print a line only once. for that we use a flag V_FLAG.

/: DEFINE &v_flag& = space

/: if &V_FLAG& = ''

/* first time this comes inside here i am passing X.

/: DEFINE V_FLAG = 'X'

• WRITE SOME THING

/: ENDIF

Hi anupma,

1. while calling subroutines from sapscripts,

there is a special technique,

which has got its own limitations.

2.

FORM abc

TABLES

in_tab STRUCTURE itcsy

out_tab STRUCTURE itcsy.

ENDFORM.

3. The perform in se38 program should be of the

above format only.

4. We cannot pass internal tables.

5. Rather we need to pass

VARIABLE NAME

VARIABLE VALUE

(see the structure of itcsy in se11)

6. In this form, we have to read

the internal table in_tab

to capture the variable name and its value.

7. Similary, to return the values,

we have to put one record (for each variable)

in out_tab.
