Hi all of You,

What is the use of ITCSY Structure ? i am having some knowledge is correct or not pls check it?

suppose i have completed the script program .every thing is fine and i missed to do sub total with out changing the code ,by using ITCSY structure we can rectify it ? or any other pls explain it what the purpose of ITCSY Structure.

Hi,

It is a structure, have 2 fields name and value and can be used to transfer data between script and program. Check the below code..

This example get the value of shipment document number based on billing document number

VBDPR-VBELN_VL is the billing document number.

In Script......

/: PERFORM GET_SHIPMENT_NO IN PROGRAM ZVADIN01

/: USING &VBDPR-VBELN_VL&

/: CHANGING &Z_TKNUM&.

/: ENDPERFORM

In program...

DATA: Z_TKNUM LIKE VTTP-TKNUM.

DATA: Z_TEMP_TKNUM LIKE VTTP-TKNUM

FORM GET_SHIPMENT_NO TABLES INTAB STRUCTURE ITCSY

OUTTAB STRUCTURE ITCSY.

READ TABLE INTAB WITH KEY NAME = 'VBDPR-VBELN_VL'.

IF SY-SUBRC = 0.

CLEAR Z_TEMP_TKNUM.

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'

EXPORTING

INPUT = INTAB-VALUE

IMPORTING

OUTPUT = Z_TEMP_TKNUM

EXCEPTIONS

OTHERS = 1.

CLEAR Z_TKNUM.

SELECT TKNUM INTO Z_TKNUM UP TO 1 ROWS

FROM VTTP

WHERE VBELN = Z_TEMP_TKNUM.

ENDSELECT.

IF SY-SUBRC = 0.

READ TABLE OUTTAB WITH KEY NAME = 'Z_TKNUM'.

IF SY-SUBRC = 0.

OUTTAB-NAME = 'Z_TKNUM'.

OUTTAB-VALUE = Z_TKNUM.

MODIFY OUTTAB INDEX SY-TABIX.

ENDIF.

ENDFORM.

Rgds,

Hi Nagi,

Normally ITCSY structure is used SAP SCRIPTS.

Suppose you are standard Driver program for your form and still you wanted to do some calculations,then you dont need to touch your standard program and in your Forms you cant write select queries also.

for this purpose, calulations and queries will be performed outside the Script and still you can bring in those values into your form.

For this pupose only ITCSY structure is used.

Thanks.

The structure ITCSY contains field name and field value.

The system does not execute the PERFORM command within

SAPscript replace modules, such as TEXT_SYMBOL_REPLACE or TEXT_INCLUDE_REPLACE.

The replace modules can only replace symbol values or

resolve include texts, but not interpret SAPscript control commands.

Syntax in a form window:

/: PERFORM <form> IN PROGRAM <prog>

/: USING &INVAR1&

/: USING &INVAR2&

......

/: CHANGING &OUTVAR1&

/: CHANGING &OUTVAR2&

......

/: ENDPERFORM

INVAR1 and INVAR2 are variable symbols and may be of any of

the four SAPscript symbol types.

OUTVAR1 and OUTVAR2 are local text symbols and must

therefore be

character strings.

The ABAP subroutine called via the command line stated

above must be defined in the ABAP report prog as follows:

FORM <form> TABLES IN_TAB STRUCTURE ITCSY

OUT_TAB STRUCTURE ITCSY.

...

ENDFORM.

The values of the SAPscript symbols passed with /: USING...

are now

stored in the internal table IN_TAB . Note that the system

passes the

values as character string to the subroutine, since the

field Feld

VALUE in structure ITCSY has the domain TDSYMVALUE (CHAR

80). See the

example below on how to access the variables.

The internal table OUT_TAB contains names and values of the

CHANGING

parameters in the PERFORM statement. These parameters are

local text

symbols, that is, character fields. See the example below

on how to

return the variables within the subroutine.

From within a SAPscript form, a subroutine GET_BARCODE in

the ABAP

program QCJPERFO is called. Then the simple barcode

contained there

('First page', 'Next page', 'Last page') is printed as

local variable

symbol.

Definition in the SAPscript form:

/: PERFORM GET_BARCODE IN PROGRAM QCJPERFO

/: USING &PAGE&

/: USING &NEXTPAGE&

/: CHANGING &BARCODE&

/: ENDPERFORM

/ &BARCODE&

Coding of the calling ABAP program:


REPORT QCJPERFO. 

FORM GET_BARCODE TABLES IN_PAR STUCTURE ITCSY 
OUT_PAR STRUCTURE ITCSY. 

DATA: PAGNUM LIKE SY-TABIX, "page number 

NEXTPAGE LIKE SY-TABIX. "number of next page 

READ TABLE IN_PAR WITH KEY 'PAGE'. 
CHECK SY-SUBRC = 0. 
PAGNUM = IN_PAR-VALUE. 

READ TABLE IN_PAR WITH KEY 'NEXTPAGE'. 
CHECK SY-SUBRC = 0. 
NEXTPAGE = IN_PAR-VALUE. 

READ TABLE OUT_PAR WITH KEY 'BARCODE'. 
CHECK SY-SUBRC = 0. 
IF PAGNUM = 1. 
OUT_PAR-VALUE = '|'. "First page 

ELSE. 
OUT_PAR-VALUE = '||'. "Next page 

ENDIF. 

IF NEXTPAGE = 0. 
OUT_PAR-VALUE+2 = 'L'. "Flag: last page 
ENDIF. 

MODIFY OUT_PAR INDEX SY-TABIX. 

ENDFORM.
