SNA Server fails to send ACTPU(ERP) and ACTLU(ERP) requests to devices
connected to SNA Server as DSPUs (Downstream PUs) even when it receives

requests to the DSPUs.
CAUSE
SNA Server was not correctly sending ACTPU(ERP) and ACTLU(ERP) requests to
DSPUs because it was ignoring the registry entries used to control how
ACTPU(ERP) and ACTLU(ERP) requests are to be handled.
