Ignore last response. I have the names wrong, they should be the result names. Sorry about that.

PRDDRA is a numeric field that I am totaling, so why is it not allowed?

Sorry, I didn’t notice that you did list the fields in the file.

Go to this link: http://publib.boulder.ibm.com/iseries/v5r1/ic2924/index.htm?info/rbam6/rbam6clmain.htm
and read the section under GROUP.

I renamed field DIV to DIVISN (I think DIV is reserved also).
I created a table identical to ELE728PF3 and called it TBL.
I then created TBLPART with the following fields:
Field
Name Type Length Dec Loc
PRPPN P 2 0 1
DIVISN A 3 3
PREMNO P 10 2 6
HRSSUM P 12 2 12
DIV# A 3 19
ACT A 3 22
OBJ A 5 25
DEBSUM P 13 2 30
CRDSUM P 13 2 37
TOTSUM P 15 2 44

Now the Group by has somewhere to put the summed values.
The other fields that are not used in this OPNQRYF statement are omitted from TBLPART.

Here is the OPNQRYF statement. Notice the FORMAT parameter:

OPNQRYF FILE((TBL)) FORMAT(TIMR/TBLPART) +
KEYFLD((PRPPN) (DIV#) (ACT) (OBJ) (PREMNO)) +
GRPFLD(PRPPN DIVISN PREMNO DIV# ACT OBJ) +
MAPFLD((HRSSUM ‘%SUM(HRS)’) +
(DEBSUM ‘%SUM(PRDDRA)’) +
(CRDSUM ‘%SUM(PRDCRA)’) +
(TOTSUM ‘%SUM(TOTAL)’))

The FORMAT parameter describes what the query result will be like. Without it, the command assumes it’s supposed to be just like the table in the FILE parameter.

Put the file layout of ELE728PF3 so we can see what it’s selecting from.

What I am trying to accomplish is to create summary records with totals for some of the fields in these records so I can print a report. The fields that I am using to total and group by are the fields it is saying can’t be there. So, I don’t understand.

When you use GROUP BY in an SQL, the columns you group by are the only columns allowed to be selected. You are grouping them for a reason. Columns other than the ones you are grouping by can’t really be shown because there could be different values for the same group.

Bottom line is that the only fields you can select from your OPNQRYF are those that you are grouping by. You can select counts or other aggregate functions for the grouped fields. SQL has ways to get around this using a subselect (or subquery).

I changed the name of the hours field and moved it further down in the record. When I reran it, it now does not like another field.

HOURS is a reserved duration keyword. So it probably does not recognize this as a field name.
