Sending Idoc to SAP, RCVPOR is missing

wm 8.0.1
SAP 6.0

When sending inbound Idocs to SAP the RCVPOR is missing for all except one scenario. But if we send another transaction to the same partner it’s missing or if we send the same transaction to another partner it’s also missing.
When I look at the transaction for that tip in the Adapter it’s present but when they get the transaction in SAP in W02 the RCVPOR is missing from the Control Record/Partner tab

Anyone encounter this?
Any ideas would be greatly appreciated at this point.
Thanks.
