[SQL7008] URLGROUP in TEFF not valid for operation.

I am connecting to an AS/400 using

   DriverManager.registerDriver(new com.ibm.as400.access.AS400JDBCDriver());
   con = DriverManager.getConnection("jdbc:as400://xxx.xxx.xxx.xxx");

<my IP here>

This prompts me for a user id & password and connects. Then I build a
listbox with the contents of a file and this works great. When I try to add
a record, I get the SQL error. My statement is

   addSql = con.prepareStatement("INSERT INTO TEFF.URLGROUP (R1KEY, R1DESC)
VALUES(?, ?)");

In my add logic I do

   try {
   addSql.setInt(1, nextKey);
   addSql.setString(2, edtField.getText());
   addSql.executeUpdate();
   }

These are the only two fields in the file. I use an SQL statement prior
to the add that gets MAX(R1KEY) and I add 1 to that. I've printed this
value to the console and it is correct.

I checked security and everything looks fine. I can't find any documentation
on this SQL error except that the SQL State is 55019. Can anyone help me
here or at least point me in the right direction. Thanks.
