I have no resolution to the issue.

Specifically, I start the debug (STRDBG) using the program name
running in the submitted job, then I add the service program as a
called module inside the debug session (using F14 to display module
list, then option 1 to add the service program). I then set the
breakpoints in the module of the service program. I set the break at
the first executable line (there is no initialization subroutine).

Thomas,
Just to be certain.
You are submitting a job which at some point runs the UDF.
You are running STRSRVJOB from a command line that specifies the
submitted job as the targeted job.
You are running the STRDBG SRVPGM(DT2ISOSRV) from the command line to
debug the *SRVPGM program containing the UDF (note the use of the
SRVPGM keyword instead of the PGM keyword on STRDBG)

Finally got back to this after a few days...
I executed a DROP function command and then a CREATE FUNCTION,
verified the function is defined in my library (using Navigator).
Here's the CREATE...
CREATE FUNCTION GARVEY/DT2ISOSRV (
TESTVALUE VARCHAR(50) ,
DATEFMT VARCHAR(4) )
RETURNS DATE
LANGUAGE RPGLE
SPECIFIC GARVEY/DT2ISOSRV
NOT DETERMINISTIC
NO SQL
CALLED ON NULL INPUT
NO EXTERNAL ACTION
NOT FENCED
EXTERNAL NAME 'GARVEY/DATE2ISO(DATE2ISO)'
PARAMETER STYLE GENERAL ;
I am trying to debug the function when it gets called by SQL, so I am
adding the Service Program (DT2ISOSRV) to my program list and setting
a break point (in DATE2ISO module). I know the function is getting
called because my job log is filled up with messages that the calls
to CEEDATE (which is called from within the function) are failing...
For example...
Timestamp picture mismatch.
The value for month is not valid.
The problem is that I can't get it to stop at my breakpoints. I
suppose that I am probably setting breaks in something OTHER than
what is actually being called, but I thought I dealt with that by
dropping the function and then CREATEing it again.
I did look at the SYSFUNCS and SYSROUTINES files and everything looks
correct.
Any thoughts?

The system does call something because each step of the original
program returns a zero in SQLCOD, AND it returns a value from the UDF.
The problem is the value is wrong and I can't get to debug the
service program to find what is going wrong.
I am not sure I understood what was being done to effect debugging,
but it seems what is described for the batch job attempts to suggest
that the UDF code being run in the batch job, is not the code being
function defines to be invoked.the breakpoint in the code chosen to debug was never hit.
For that... The output from a TRCJOB would show what specific code
was being run; and presumably would be again on the next run.
Consider that the library list is less relevant if the SQL PATH is
not *LIBL, and furthermore if the EXTERNAL NAME for the routine
directs to a specific [a qualified] service program name [which could
be outside of the library list]. What specific version of the
function being invoked is the first thing to determine, then what that
SYSROUTINES.Library qualifying the function is best to ensure the former, and
that also makes finding-out the latter easier, by a very specific
query of the catalogs.
The CREATE FUNCTION was not offered nor any variants either for
SPECIFIC name or SOURCED; i.e. there might be overloaded or effective
duplicates defined. Verify the routine definition(s) in SYSFUNCS or
