Order Entry type form to add to three tables
in [Tables]
|
From: CuriousMark on 8 Feb 2010 18:04 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.

How can this be as your query for main form does not have OrderID field. >>how to search based on the entry for an existing customer, 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 QTY – Size – Color - -- Build a little, test a little.

From: Steve on 8 Feb 2010 19:37 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!!!

From: Jeff Boyce on 8 Feb 2010 19:52 These newsgroups are "staffed" by (mostly) volunteers. The Code of Conduct precludes soliciting paid work. 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!
