SQL Error 01004

I'm getting this error inside my RPG program... I'm selecting 4 fields from one file into 4 fields in my program (which are defined by reference to fields in another file). I think the error is related to the time fields... but they are both defined the same.

All 4 fields in the "select into" are being populated correctly. However, my Sql State is 01004. Any ideas what could cause this? I'm on v7r3.

Code snippet:

Ompckr char(8)
Omplin packed(5:0)
Ompitm packed(5:0)
Ombgtm time(*iso) - defined as "T" in the file

(ALL fields are defined by reference to fields in a Physical file)

Exec Sql
Declare rfcsr Cursor for
Select aauser, count (distinct bbprt#), sum(bbqty#), min(aatime)
From RFPCKRBB
Join RFPCKRAA on aabid#=bbbid#
Where... Etc..

Exec Sql Open rfcsr;
Dou noRows;
Exec Sql Fetch Next from rfcsr
Into :ompckr, :omplin, :ompitm, :ombgtm;

If SqlStt <> SqlOk;
noRows = *on;
iter;
Endif;
