The Program runs as a standard Batch Job with Multiple CSECTS and has an RB.
Why do I always get Zeroes in SDWAEPA ?

I don't see a field called "Offset" in the SDWA so I suspect that needs to be
calculated, but with out an Entry Point Address (EPA) I cant' calculate it.

Can some shed some light on my lack of understanding of this ?

We don't use SDWAEPA 'cause it is zero sometimes (don't know why).
We check to be sure bit SDWARPIV is OFF in the SDWAERRD byte, and if it
is, we use the rightmost four bytes of the SDWACTL1 field as the address
of the next instruction @ time of ABEND.
Using that information you can see if the failure was in your ESTAE exit
itself or not. If not, then you can use a combination of the address of
the next instruction and breadcrumbs passed to your ESTAE exit via
SDWAPARM to determine which CSECT was executing at the time of the
ABEND. SDWACMPC helps you decide if the ABEND is worth retrying or not.
