Question on embedded SQL in RPG with Update

I am trying to do an update while in a loop with embedded SQL in RPG.

When I enable the update, SQLSTATE returns 24501 and nothing seems to be put
in the buffer.

When disable the update, it runs fine.

I cannot find any examples of updating using embedded SQL.
I have the file format referenced in the UPDATE. I had the name of the
physical file.
Worked the same. I also tried using the name of the external data structure,
same results.

Here is my code:

FQsysprt O F 120 PRINTER OFLIND(*InOF)
DPRODOCKE E DS EXTNAME(XXXPY70P)
C/EXEC sql
C+ DECLARE A CURSOR FOR
C+ SELECT *
C+ FROM XXXPY70P
C+ WHERE SUBSTR(DEDSC1, 68, 3) > ' '
C+ AND SUBSTR(DEDSC1, 70, 1) <> 'N'
C/end-exec
C/EXEC sql
C+ OPEN A
C/end-exec
C SQLSTATE Downe '02000'
C/EXEC sql
C+ FETCH A INTO :PRODOCKE
C/end-exec
C If sqlstate='02000'
C leave
C Endif
C/exec sql
C+ update xxxpy70f <<< when enabled, no recs
end up in buffer
C+ set dedsc1= substr(dedsc1,1,67) CONCAT ' ' <<< disabled, prints all
recs that qualify
C+ WHERE CURRENT OF A
C/end-exec
C** except print
C Enddo
C/EXEC sql
C+ CLOSE A
C/end-exec
C eval *inlr=*on
OQsysprt E print 2
O deccy
