SAPRFC Can't find interface name

[peter_kamenik]

Hello developers,

first of all its good to see that a PHP-SAP development still lives! And now to my question:

we have a certain function module that is being called from an third party application. For our development needs we need to see the raw data coming from the RFC call so I went back to roots, installed apache, php and so on. Now, the hello world (SE16 emulator) works fine, I got the data from tables. However adopting the script to my function return:

Warning: CALDBG: Can't find interface name ZDATA, __cal_refresh_internal_buffer() in ...SAP_Connection.php on line 61

line 61:

saprfc_table_init ($fce,"ZDATA");

The function module I call is defined like this:

FUNCTION Z_PROD_DATA.
*"----------------------------------------------------------------------
*"*"Lokální rozhraní:
*"  IMPORTING
*"     VALUE(S_FBUDA_FROM) TYPE  FBUDA OPTIONAL
*"     VALUE(S_FBUDA_TO) TYPE  FBUDA OPTIONAL
*"     VALUE(S_AESZN) TYPE  AESZN OPTIONAL
*"  TABLES
*"      ZDATA TYPE  Z_PDATA
*"----------------------------------------------------------------------
tables: vbrp, vbpa, konv, vbfa.

data: begin of ivbrp occurs 0 ,

and the relevant part of the php script looks like this:

//Try to connect to SAP using our Login array
   $rfc = saprfc_open ($LOGIN);
   IF (! $rfc )
   {
       ECHO "The RFC connection has failed with the following error:".saprfc_error();
       EXIT;
   }

//We must know if the function really exists
   $fce = saprfc_function_discover($rfc, "Z_PROD_DATA");
   IF (! $fce )
   {
       ECHO "The function module has failed.";
       ECHO $rfc;
       EXIT;
   }
var_dump($fce);

//Pass import parameters
   saprfc_import ($fce,"S_FBUDA_FROM",$_POST['S_FBUDA_FROM']);
   saprfc_import ($fce,"S_FBUDA_TO",$_POST['S_FBUDA_TO']);
   saprfc_import ($fce,"S_AESZN",$_POST['S_AESZN']);
//Pass table parameters
//   saprfc_table_init ($fce,"OPTIONS");
//   saprfc_table_init ($fce,"FIELDS");
   saprfc_table_init ($fce,"ZDATA");

ending with the above mentioned line 61.

I cant use webservices for this. Any ideas what I am doing wrong?

Thank you

Hi Peter,

Just wondering about the way the table ZDATA has been declared: I would expect the following:

FUNCTION Z_PROD_DATA .
*"----------------------------------------------------------------------
*"*"Local Interface:
*"  IMPORTING
*"     VALUE(S_FBUDA_FROM) TYPE  FBUDA
*"     VALUE(S_FBUDA_TO) TYPE  FBUDA
*"     VALUE(S_AESZN) TYPE  AESZN
*"  TABLES
*"      ZDATA STRUCTURE  Z_PDATA
*"----------------------------------------------------------------------

Maybe this could be of some help.

Thank you and bye,

Flavio

Thans, that actually helped. I am getting the correct ouput.
