call_and_receive fires 2 times?? why ??

florian_endres · ‎03-11-2008

Hello,

i have little problem with saprfc_call_and_receive().

In Firefox (2+) everything is ok. call_and_receive() fires only 1 time.

BUUUUUUT with IE (6+) the same call_and_receive() fire 2 times.

1. Firing => RCODE = 0 (OK)

2. Firing => RCODE = 4 (BAD) because datarow is already in DB.

PHP 5.1.1

SAPRFC_PHP 1.4.1

Any suggestions???


<?PHP

$login = array (	
                                        <passing logon data>
			);
			
$rfc = saprfc_open ($login );                                                                                
//We must know if the function really exists
$fce = saprfc_function_discover($rfc, "<function_name>");
if(!$fce){
	echo "The function module has failed.";
  echo $rfc;
  exit;
}

//Pass table parameters
saprfc_table_init ($fce,"<table_name");

//setting IMPORT-Param
$set_import = saprfc_import ($fce,"SPRAS",$SPRAS);

foreach ($new_data as $data){
  saprfc_table_append ($fce,"table_name", <building my array>);
															 
}

//Call and execute the function
$rc = saprfc_call_and_receive ($fce);

//wenn etwas auf Fehler läuft wird dieser ausgegeben.
switch ($rc) {
   case SAPRFC_OK        : break;
   case SAPRFC_EXCEPTION : echo "Exception raised:".saprfc_exception($fce)."<br>";
                           // handle exception
   default              : echo "RFC error ".saprfc_error()."<br>";
                           exit;  
}

?>

<html>
<head>
</head>

<body>
<?PHP
	$RCODE = saprfc_export ($fce,"RETURNCODE");
	$MESSAGE = saprfc_export ($fce,"MESSAGE");
      
//if $RCODE =4 Errormessage $MESSAGE
	if ($RCODE == "4") // Fehler
	{
                <PHP-Coding>
	}
	else
	{
		<PHP-Coding>
	} // if ($result == "" )

saprfc_function_free($fce);
saprfc_close($rfc);
?>
</body>
</html>

thanx

Hello,

It's not that easy.

My prior page calls the update page only 1 time.

I think some freaky dll form the IE fires the call_and_receive 2 times.

Some debugging on the update page give me this result.


Function module: /FIS/MON_SET_VERTRETER (remote SAP R/3: 700 Unicode)
IMPORT
CHECK_AUTGEN /o/  C 1 0 offset = 0 
SPRAS  C 1 0 offset = 0 
EXPORT
MESSAGE  C 72 0 offset = 0 
RETURNCODE  b 1 0 offset = 0 
TABLE
VERTRETERLISTE MANDT C 3 0 offset = 0 
 EMPFAENGER_EMAIL C 128 0 offset = 3 
 ZEIT_VON D 8 0 offset = 131 
 ZEIT_BIS D 8 0 offset = 139 
 KZ_GRUNDSAETZLIC C 1 0 offset = 147 
 VERTRETER_EMAIL C 241 0 offset = 148 
 VERTRETER_SAPUSE C 12 0 offset = 389 
 DB_MODE C 1 0 offset = 401 
Value of import (input) parameter CHECK_AUTGEN (optional) (memory = 1):
""
Value of import (input) parameter SPRAS (memory = 1):
"D"
Value of export (output) parameter MESSAGE (memory = 72):
""
Value of export (output) parameter RETURNCODE (memory = 1):
"0"
Internal table VERTRETERLISTE (memory = 408):
MANDT EMPFAENGER_EMAIL ZEIT_VON ZEIT_BIS KZ_GRUNDSAETZLIC VERTRETER_EMAIL VERTRETER_SAPUSE DB_MODE 
"500" "balaba@FIS-GMBH.DE" "20080505" "20080505" "" "fdsahgfdaga@gfdg.de" "" "I" 
1 rows

When the prior or update page fires the call_and_receive 2 times, should i see this debug info twice?

thanx

hi florian,

you are aware of the fact, that your your PHP script and especially the RFC function in question is executed at the webserver and therefore independent of the browser used, right?

so, IMHO, the only way to get your problem is to call the script twice by some client side coding (HTML form and/or javascript in parallel). But you show only pseudo-coding for the client side.
