Problem with decaring formal parameters

Former Member — Fri, 07 Jul 2006 15:06:59 GMT

Hello,

I have written the following piece of code:


 FORM PC_SSL_UPLOAD USING WA_UPLOAD_DATA LIKE LINE OF LT_UPLOAD_DATA
                          CHANGING P_UPLOAD_DATA TYPE STANDARD TABLE OF TY_UPLOAD_DATA.

where LT_UPLOAD_DATA was declared as an internal table of type TY_UPLOAD_DATA.

When I tried to do a syntax check, I've got the following message:

Different number of parameters in FORM and PERFORM (routine:PC_SSL_UPLOAD, number of formal parameters: 4, number of actual parameters: 2).

I thought all I have declared was 2 formal parameters: WA_UPLOAD_DATA as the work space and P_UPLOAD_DATA as the parameter, why there are 4 parameters? and how can I change the code such that it works the way I intend to get it to work?

Thanks a lot!

Regards,

Anyi

hi,

do this


FORM PC_SSL_UPLOAD 
     tables P_UPLOAD_DATA 
     USING  WA_UPLOAD_DATA type TY_UPLOAD_DATA

or 

FORM PC_SSL_UPLOAD 
     tables P_UPLOAD_DATA  like <original table name>
     USING  WA_UPLOAD_DATA type TY_UPLOAD_DATA

Note :- whatever u use in type or like should be global; that is accessable in the form

Please try it like this.



types: begin of ty_upload_data,
       str type string,
       end of ty_upload_data.

data: i_upload_data type table of ty_upload_data.
data: wa_upload_data like line of i_upload_data.


perform pc_ssl_upload tables i_upload_data
                      using wa_upload_data.



*---------------------------------------------------------------------*
*       FORM PC_SSL_UPLOAD                                            *
*---------------------------------------------------------------------*
*       ........                                                      *
*---------------------------------------------------------------------*
*  -->  WA_UPLOAD_DATA                                                *
*  -->  P_UPLOAD_DATA                                                 *
*  -->  OF                                                            *
*  -->  TY_UPLOAD_DATA                                                *
*---------------------------------------------------------------------*
form pc_ssl_upload  tables p_upload_data structure wa_upload_data
                     using wa_upload_data structure wa_upload_data.




endform.

p_upload_data should be a TABLES parameter and not CHANGING.

PERFORM PC_SSL_UPLOAD USING W_UPLOAD_DATA TABLES T_UPLOAD_DATA .

FORM PC_SSL_UPLOAD

USING PW_UPLOAD_DATA LIKE LT_UPLOAD_DATA

TABLES PT_UPLOAD_DATA STRUCTURE LT_UPLOAD_DATA.

ENDFORM

Hi Anyi,

It is always better if you write your perform statement and then double click on the form name to create the form routine by itself.

perform pc_sll_upload using <data> tables <itab>.

double click on the pc_sll_upload to create a form routine.

Ravi

Or you can do this too. Using a table type and changing .



types: begin of ty_upload_data,
       str type string,
       end of ty_upload_data.

<b>Types: ty_tab_upload_data type table of ty_upload_data.</b>

data: i_upload_data type table of ty_upload_data.
data: wa_upload_data like line of i_upload_data.


perform pc_ssl_upload
                      using wa_upload_data
                     <b> changing i_upload_data.</b>



*---------------------------------------------------------------------*
*       FORM PC_SSL_UPLOAD                                            *
*---------------------------------------------------------------------*
*       ........                                                      *
*---------------------------------------------------------------------*
*  -->  WA_UPLOAD_DATA                                                *
*  -->  P_UPLOAD_DATA                                                 *
*  -->  OF                                                            *
*  -->  TY_UPLOAD_DATA                                                *
*---------------------------------------------------------------------*
form pc_ssl_upload
                     using wa_upload_data structure wa_upload_data
                    <b> changing p_upload_data type ty_tab_upload_data</b>.




endform.

Hi use Structure

DATA: wa_upload_data like line of lt_upload_data.

FORM PC_SSL_UPLOAD TABLES p_upload_data structure wa_upload_data

USING P_UPLOAD LIKE wa_upload_data

Hi,

Thanks for all the replies.

However, when I tried to use USING...CHANGE way, like what Rich has suggested, I got an error message like this:

In PERFORM or CALL FUNCTION "PC_SSL_UPLOAD", the actual parameter "LT_UPLOAD_DATA" is incompatible with the formal parameter "P_UPLOAD_DATA".

However, I did declare the LT_UPLOAD_DATA like this:

 DATA: LT_UPLOAD_DATA TYPE STANDARD TABLE OF TY_UPLOAD_DATA,

And I am pretty sure I declared P_UPLOAD_DATA as:

CHANGING P_UPLOAD_DATA TYPE TY_UPLOAD_DATA

So where is the problem now?

Thanks!

Anyi
