Load balancing and RFC problem

Former Member — Mon, 04 Aug 2008 11:53:04 GMT

Hi!

I have a problem regarding load balancing and RFC's. We use the follow function in librfc32.dll (from VB6) for RFC calls: RfcOpenExt It's working fine no problem, but from now on we will have to use the this funcion due to load balancing: RfcOpenExtV3

The only difference between the two functions is the parameters. RfcOpenExtV3 has 5 additional parameters:

intLoadBalance1, strLbHost1, strLbSysName1, strLbGroup1, intSapGui1

I asked our tech guys for the details so that I can set up the parameters (double check everything) and the RfcOpenExtV3 doesn't working. Return value is zero.

Have somebody faced with this issue before?

Thanks in advance!

Hi! Thanks for the feedback! I already checked this help page and tried to modify the parameters but the return value is still 0, so no connection....
