ReportingMth date,
customer_id varchar(50),
ReferenceID navarchar(50),

set lastorderte = sls.max_orderdte
from ( select
st.customer_id,
ftmytbl.ReportingMth,
max(salesdate) as max_orderdte
from sales_table st
left outer join mytable ftmytbl
on ftmytbl.customerid=st.customerRef
where saleste<=ftmytbl.ReportingMth
group by customer_id
)up

and mytable.reportingmth=up.ReportingMth;
end;

Answer 1

Search for that text. Where is it? It is in the where clause of the outermost select statement. You used a derived table named up (which is a crap name, btw - as are many of your names) in the join. The outer query knows only 2 tables - up and MyTable (or is it mytable? BE CONSISTENT!) and can only refer to columns in those tables.
To correct this particular problem, change this:
and mytable.reportingmth=up.ReportingMth;
to
and MyTable.ReportingMth = up.ReportingMth;
But that will only fix one problem. There seem to be others yet to be found.
