you're right, I did not see reservation ...
so do the same (left join)
reservation
left join
reservatio ... (I do not see the whole name in diagram)
left join sales with invoice line:
invoice line
left join
sales
let me know
Hi,
You can resolve this issues by solving Synthetic keys and circular loops problem
Synthetic Keys

Circular Loop

Still the loop is there.
Please advise.

Hi,
If you are using multiple keys in the table then by unique key join the table or you can make composite keys
Eg:-
Load
Field1&'_'&Field2 as Key
..
..
..
From Source;
Note :- Also load table one by one by using Exit script; at the end of load script.

Anand
Still the same and appeared synthetic keys.
hi,
comment sl-id from region_sline and service_id from invoice_line.
cheers

I used Loosen function by removing joins.
Now there is no loops. Is this good practice?
Invoice_Line:
LOAD inv_id,
service_id,
days,
nb_guests
FROM
C:\Island Marketing\Invoice_Line.QVD
(qvd);
Loosen table Invoice_Line;
//LEFT JOIN
Sales:
LOAD inv_id,
cust_id,
invoice_date
FROM
C:\Island Marketing\\Sales.QVD
(qvd);
hi,
I haven't used 'loosen table' command but, from what I've heard it is not a good practice. i go for rather traditional approach.
cheers,
