SQLRPGLE Fetch with Null field values

Hi all, I need help!
I'm trying to run a SQLRPGLE program with a Fetch Into clause with
possible null values.

The Select statement (skinnied down) is as follows:
Sel = 'Select oh, +
a.WHSE, a.SKU, a.HANDLCDE, a.COORDGRP, a.OH#MMS, +
From @SISYNWRK a left join @synppoh1d on a.sku = icmpno +
Where ( a.Flg_01 = '' '' and a.flg_08 = '' '') +

and a.Whse = ? and a.sku not in (select isetno from sethdr) ';


The Fetch is
Fetch Next from SelectStmt into :DSSis800

The host variable DSSis800 is defined as
d DSSis800 e ds extname(@SIS800WPF)

and the field OH is defined in DDS as 6S 0 with ALWNULL and DFT(0)

When I run the program I get a message "Indicator variable required."
and no data is copied.

How can I get this to populate the external data structure (I run the
Fetch through a Do Loop and write to the file), or how do I define an
"Indicator variable" for the null-capable field?

Thanks,
