The code I am getting this error is as follows:

,max(Case WHEN (ls_code = ''924'' and ls_scheduled_completion_date <> (''01/01/1900'')
             then ls_scheduled_completion_code
               else NULL End) as Ls_scheduled_completion_date

,max(Case WHEN (ls_code = ''926'' and ls_scheduled_completion_date <> (''01/01/1900'')

Answer 1

Don't you mean LS_SCHEDULED_COMPLETION_DATE ?

There doesn't appear to be a LS_SCHEDULED_DATE anywhere in the query other than in the on and group by clauses where I'm assuming the error is occurring.

From IBM's own publib site :

For a SELECT or DELETE statement, the specified column is not a column of any of the tables or views identified in a FROM clause in the statement.

Verify that the names are specified correctly in the SQL statement. For a SELECT statement, ensure that all the required tables are named in the FROM clause.
