Attribute QUEUE_NAME is initial Error

Hallo,

when I´m calling an BAPI over RFC and with QoS=EOIO then the following error occure:

Result:

<SAP:Error>

<SAP:Category>XIServer</SAP:Category>

<SAP:Code>INTERNAL.ATTRIBUTE_INITIAL</SAP:Code>

<SAP:P1>QUEUE_NAME</SAP:P1>

<SAP:Stack>Attribute QUEUE_NAME is initial</SAP:Stack>

</SAP:Error>

I made the RFC-Destination with the correct SAP-System; must i create a queue for this destination? And when yes how i can do this? I need an outbound-queue - yes?

Thanks in advance,

Frank
