SQL tables do not include keys ... unique keys on an SQL Table are
implemented over a primary key constraint or over an additional unique key
index.
Since you are not changing any columns and not adding or removing any
columns, adding a key column will not affect any RPG program, even if the
table is not defined with level check *NO.
In either way I'd change the table to level check *YES, check the RPG
programs and recompile them.

Subject: DDL table add key column?
I have an existing DDL table with level check set to *NO. The table has a
unique key over three columns. I need to add a fourth key column (at the
end). I'm fairly certain this won't harm any RPGLE programs that have it
defined on a File spec, but I'm hoping to get a second opinion. Am I safe
in adding that key column?
TIA
