FABH0412E VIRTUAL PAIRED SEGMENTS NOT SUPPORTED
Because of PSBGEN specifications, an HSSR PCB containing a sensitive logical child that is virtually paired. Virtually paired segments are not supported by HSSR Engine.
HSSR Engine issues a SNAP for this PCB and falls back to DL/I. The PCB is defined as a DL/I PCB, and all calls issued against it are processed by DL/I action modules.
Modify the virtually paired segment to, for example, a physically paired segment, or remove the SENSEG statement of the virtually paired segment from the PCB, or do not specify the PCB as an HSSR PCB.
