SAP SCRIPTS : Want to display item data, by using PERFORM from SAP SCRIPT

[Former Member]

Hi All,

I am calling a sub-routine in a INCLUDE PROGRAM <b>'ZTEST'</b> form a sap-script using a PERFORM STATEMENT.

The data which i retrive inside this sub-routine in my include<b>'ZTEST'</b> is coming in an internal table and I have to display all the entries of the internal table.

I am trying to define a element <b>'DISPLAY_ITEM'</b> inside the sap-script and trying to call that in a loop inside my INCLUDE program using WRITE_FORM. But nothing getting printed after the new element<b>'DISPLAY_ITEM'</b> which i have defined and was calling from the INCLUDE PROGRAM.

Hi kaushal,

1. while calling subroutines from sapscripts,

there is a special technique,

which has got its own limitations.

(It should be program of type 1, and not an include)

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.

amit m.

Hi Kaushal,

You cannot pass/ get values in the form of internal tables using performs in sap scripts.

Instead you can keep this perform in a text element which is being called in the loop of an internal table.

Hi,

Have a look at the example for calling subroutines from script.

http://www.sap-basis-abap.com/abap/how-to-call-a-subroutine-form-sapscripts.htm

Hope this helps.

hi,

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.

endform.

Sailaja.

Hi Kaushal,

when you create Perform and Endperform, you can transfer the fields one by one, you can not transfer entire Internal table in one shot,

When you write the perform statment in Script, use CHANGING variables

/: PERFORM <form> IN PROGRAM <prog>

/: USING &INVAR1&

/: CHANGING &OUTVAR1&

/: CHANGING &OUTVAR2&

/: CHANGING &OUTVAR3&

/: CHANGING &OUTVAR4&

......

/: ENDPERFORM

in your Program <b>ZTEST</b>, while calling

FORM <FORM> TABLES IN_PAR STRUCTURE ITCSY

OUT_PAR STRUCTURE ITCSY

Read the IN_PAR table to get the values ..

while putting the values to outtab, loop that internal table and pass to the Output table to the CHANGING parameters in SCRIPT,

ENDFORM

hope you understand
