Order Entry type form to add to three tables

I have been working on this database for several years, learning as I go.
However I have been stuck on the problem of the best way to design a form for
data entry into three tables. I now give up and put the whole thing on the
Forum in the hope that someone can help me with the design. For simplicity, I
will illustrate using the "Order Entry" style database, and limit the fields
to only those necessary.

There are four tables with the following fields:

tblCustomers - CustomerID (pk), CustomerName
tblOrders - OrderID (pk), OrderDate, CustomerID (fk)
tblOrderProd - OrderProdID (pk), OrderID (fk), ProductID (fk)
tblProducts - ProductID (pk), ProductName

One customer is associated with one or more orders, and one order can have
one or more products. The user should be able to create a new order by
specifying the date and the customer, and then one or more products.

I have a main form with subform to do this. The main form is bound to a
query that joins the tblOrders and tblCustomers tables, and the subform is
bound to a query that joins the tblOrderProd and tblProducts tables. The
subform is linked to the main form through the OrderID field.

Main form query:
SELECT tblOrders.OrderDate, tblCustomers.CustomerName
FROM tblCustomers INNER JOIN tblOrders
ON tblCustomers.CustomerID = tblOrders.CustomerID

Subform query:
SELECT tblOrderProd.ProductID, tblProducts.ProductName, tblOrderProd.OrderID
FROM tblProducts INNER JOIN tblOrderProd
ON tblProducts.ProductID = tblOrderProd.ProductID

This setup works great for adding records, and when I enter a ProductID in
the subform it will show the ProductName but the problem is that this design
means a new customer is added for each new order: I can't figure out how to
search based on the entry for an existing customer, use it if it exists, or
add it if it is new.

My hunch is that I should unbind both forms, using Append queries to enter
the data in the related three fields. If so, then how do I find out the new
OrderID to use to append to tblOrderProd? And how do I find out the
CustomerID to use to append to the tblOrders if it is a new Customer? Then
how do I progress through each ProductID entered in the subform when
appending to the tblOrderProd table?

Thanks very much.
 
The subform is linked to the main form through the OrderID field.
How can this be as your query for main form does not have OrderID field.
Use a combo to select customer.

Main form – tblOrders - tblCustomers
Combo – select customer
Enter OrderDate - automatic generate OrderID
- required delivery - payment - shipping method - etc.

Make sure you set the Master/Child links on form/subform on OrderID.

Subform – tblOrderProd - tblOrders - tblProducts
Combo – select product

Hello Mark!

You deserve an A+ for Stick-To-It ness for working on the database for
several years. However, wouldn't it be a relief to get it done and move on?
I would like to offer to work with you and finish your database. I provide
help with Access, Excel and Word applications. My fee to finish the database
with you would be very reasonable. Contact me and let's get it done!!!

Before you sign any contracts, you might want to consider whether you want
to hire someone who doesn't feel it necessary to follow the rules.

Why do you have a main form with Customer and Order joined? If the main
form is your Order form, you can use a combobox to list possible customers
and select which one it is, to add to your Order record (customerID).

If you'd rather have Customer as your main form, your Order is your subform
and the OrderDetail is the subsubform.

Using subforms and the Parent/Child joins between main and sub (and between
sub and subsub) will allow Access to properly record the "parent" to which a
particular Order Detail or Order belongs

Good luck!

was any good, the "thousands" of people he claims to have helped would be
flooding him with work, but there appears to be a continuous drought and he
needs to constantly grovel for work.

The OrderID field is autonumber generated as soon as data is entered in the
form.
Use a combo to select customer.

Main form – tblOrders - tblCustomers
Combo – select customer
Enter OrderDate - automatic generate OrderID
- required delivery - payment - shipping method - etc.

how do I have it add a new customer if the customer doesn't exist?
 
Steve,

Thanks but not thanks. I guess you don't understand.....I wouldn't have
learned as much as I have if I just hired someone else to do it for me. That
takes all the fun and learning out of it.
 
Thanks Jeff.
Agreed that the form should be based only on the tblOrders table, with a
combo box for Customer. But I couldn't figure out how to add new customer if
one didn't exist.
 
Check Access HELP for NotInList and LimitToList.

There are examples of the code you'd use to pop open a "new customer" form
to add a new one before returning back to the Order form.

Thanks Jeff, I'm familiat with that approach but I'm trying to do something a
little different....
I want to be able to enter the "Customer" information on the same form,
without having to open a new form, so I have several fields for the customer
on the "Order" form. I also want the program to search for matches on several
of the "Customer" info fields, not just one combo box. The best way I can
think to do it is to use an unbound form and run a query after data is
entered into one of the fields used for searching. Then using an Append Query
to add the data to the appropriate table.
 
Hey, whatever works!

Best of luck
