Hello,
 
I have 2 TABLES from 2 different DATABASES.
 
TARGETCUSTOMERS table is an excel spreadsheet with fields:
CODE
ACCMANAGER
TARGET
 
CUSTRANSACTIONS table is located on our main database with fields
CODE
QTY
INVOICENUMBER
BRAND
etc etc.... (basically all the transaction data)
 
 
I have set up the report, and linked the tables like:
 
TARGETCUSTOMERS.CODE --->  CUSTRANSACTIONS.CODE  
(Left outer join) (Not enforced)
 
 
problem:
 
Grouped by TARGETCUSTOMERS.CODE.
 
these are a few accounts in the TARGETCUSTOMERS table:
 
4PBTREB
4PENTO
4PENISTO
4ROGER
4ROGBAR
 
When I drop the CUSTRANSACTIONS.QTY field into the groupheader,
 
4PENISTO dissapears from the report.
 
The select expert filters to only show the last 3 months data, and 4PENISTO has not purchased anything in the last 3 months, which would mean that there is no data to display.
 
But I thought, using the LEFT OUT JOIN to link the tables, would still show this customer in the report, but with a 0 qty.
 
 
Am I missing something simple here? do I need to include some isnull somewhere?
 
 
I dont have this problem when I have done similar linking before, BUT previously I have only ever used tables from the same database.
 
 
Can anyone help?
 
 
Regards,

Michael Jones

when you used the field from your other table it automatically 'enforced' the join and changed your dataset.

How can I ressolve it? so it displays all customers in the TARGETCUSTOMER table regardless of whether it has matching data in the TRANSACTION table or not.

try reversing your join.

however I think I remember reading somewhere that using excel as a source will not allow for outer joins...
