I agree that SQL function makes more sense in this case but one thing I do
notice is that you are declaring the return variable as Integer in the SQL
but declaring as Small Integer in the RPG program. That might cause some
excitement. You need to code the RPG as Int(10).

I find it a lot easier to code SQL functions in SQL. No need for RPG. If
you have to, the SQL code can call an RPG program .

then use SPECIFIC to assign the name of the service program the system
creates for the sql function. That makes it relatively easy to debug using
STRDBG.

here is a sample SQL function:

CREATE OR REPLACE FUNCTION dwhpf30c_isDropShip(
inCucode char(6),
inOrdnum decimal(9,0))
RETURNS char(1)
language sql
SPECIFIC DWHPF30CFB
SET OPTION DATFMT = *ISO, DLYPRP = *YES, DBGVIEW = *SOURCE,
USRPRF = *OWNER, DYNUSRPRF = *OWNER, COMMIT = *CHG
BEGIN

DECLARE VMSG CHAR(80) ;
DECLARE VCMDSTR CHAR(256) ;
declare vCount int default 0 ;

select count(*)
into vCount
from dwhpf30d a
where a.ordcust = inCucode and a.ordordnum = inOrdnum
and a.ordwhc = 'PNY'
fetch first row only ;
if vCount > 0 then
return 'Y' ;
else
return 'N' ;
end if ;

END

I have a program that takes a manifest# and a pick ticket# and returns a
qty. I would like to have it as a UDF so I could use it to UPDATE a
table
with that info.

I found some info on the great rpgpgm.com, so I wrote my UDF wrapper.
My Full code here, https://code.midrange.com/9430223040.html,

Snip here
dcl-proc GetPPKQty export ;
dcl-pi GetPPKQty int(5);
ppManifest zoned(8) const ;
ppInvoice char(16) const;
end-pi ;
dcl-s outPcs int(5) ;

My SQL Create
CREATE OR REPLACE FUNCTION WHSLIB.WHSO643R (ppManifest
DECIMAL(8,0),ppInvoice Char(16))
RETURNS INT
LANGUAGE RPGLE
DETERMINISTIC
NO SQL
EXTERNAL NAME 'WHSLIB/WHSO643R(GETPPKQTY)'
PARAMETER STYLE GENERAL
PROGRAM TYPE SUB ;


When I try to run my SQL update I get a decimal error.

select sdinvoice, sdmanif#, sdqty, whso643r(sdmanif#,sdinvoice)
from xxxr021

I tried to STRDBG on the UDF but that I get Pointer not set for location
referenced.
