Re: Alphabetizing detail records to a header file

Did I miss something here?  When I  "Select the Alpha Name from the secondary 
file (Header) as the key" I  got 
a halt saying the key must be from the first file on the left.  If I move 
the huge file to the left side I am expecting huge performance problems 
although I admit I haven't tried it yet.  Any ideas what I missed?

If I understand the question, create a logical or view withthe DETAIL file 
as the
primary file joining to the Header file. The join would be on the "arrival
sequence Unique ID number field". Select the Alpha Name from the secondary 
file
(Header) as the key. The max reads would be the total number of records in 
the
detail file. It sounds like you have used the JDFTVAL keyword in your 
join, in
which case  the join is backwards, resulting in a view with the total 
number of
records equal to the number of records in the Header file (unless you use 
an
Inner Join which would result from no JDFTVAL keyword.)

The logical below should work. Let us know if it does the trick.
