Calling form from layout.

Former Member — Fri, 05 Oct 2007 10:35:45 GMT

In a layout, I have the following perform statement :

PERFORM CONVERT_CURRENCY IN PROGRAM Z_SCRIPT_INVOICE

USING &ZRATE&

USING &ZKBETR&

USING &ZKWERT&

USING &ZCURRENCY&

USING &VBDKR-WAERK&

USING &VBDKR-BUKRS&

USING &KOMVD-KAWRT&

USING &VBDKR-VKORG&

USING &VBDKR-LAND1&

CHANGING &ZPRICE&

CHANGING &ZAMOUNT&

ENDPERFORM.

But form statement is as follows:

FORM convert_currency TABLES input_tab STRUCTURE itcsy

output_tab STRUCTURE itcsy.

ENDFORM.

- Plz explain how the parameter is matched between form & perform?

The program Name in the PERFORM is Z_SCRIPT_INVOICE

So in SE38 You will create this program and in that you will write the FORM..ENDFORM.

So when the PERFORM is executed it calls the PROGRAM in SE38 and the form is called.

In form you write READ Table IN_PAR with key 'ZRATE'.

See the sample code

How to call a subroutine form SAPscripts

The Form :

/:PERFORM CDE_CENT IN PROGRAM ZKRPMM_PERFORM_Z1MEDRUCK

/:USING &EKKO-EBELN&

/:CHANGING &CDECENT&

/:ENDPERFORM

The report :

REPORT zkrpmm_perform_z1medruck .

DATA : BEGIN OF it_input_table OCCURS 10.

INCLUDE STRUCTURE itcsy.

DATA : END OF it_input_table.

déclaration de la table output_table contenant les

variables exportées

DATA : BEGIN OF it_output_table OCCURS 0.

INCLUDE STRUCTURE itcsy.

DATA : END OF it_output_table.

DATA : w_ebeln LIKE ekko-ebeln,

w_vbeln LIKE vbak-vbeln,

w_zcdffa LIKE vbak-zcdffa.

*----

FORM CDE_CENT

*----

FORM cde_cent TABLES input output.

it_input_table[] = input[].

it_output_table[] = output[].

READ TABLE it_input_table INDEX 1.

MOVE it_input_table-value TO w_ebeln.

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'

EXPORTING

input = w_ebeln

IMPORTING

output = w_ebeln.

SELECT SINGLE zcdffa FROM ekko

INTO w_zcdffa

WHERE ebeln = w_ebeln.

it_output_table-name = 'CDECENT'.

MOVE w_zcdffa TO it_output_table-value.

MODIFY it_output_table INDEX 1.

output[] = it_output_table[].

ENDFORM.

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.

Example:

In script form

/: PERFORM READ_TEXTS IN PROGRAM 'Z08M1_FORM_EKFORM1'
