By Richard Rost     8 years ago

Microsoft Access Expert Level 8 is 1 hour, 55 minutes long and focuses beginning to build our Order Entry System. We'll start out by learning how to create Calculated Query Fields.

We'll build an Order Form and Order Details Form (for line items), and lots more. Topics include:

- Order Entry System
- Order Form and Details Subform
- Calculated Query Fields
- Figuring Sales Tax if Taxable
- IIF Function (If/Then/Else)
- Proper Rounding of Values
- Bankers Rounding
- Nesting Functions
- Final Product and Tax Totals

Why would you calculate the sales tax on each line?  Shouldn't the sales tax be calculated on the sum of the extended price of all taxable items?
 Richard Rost 3 months ago It's the same either way. (1+2+3+4)*10% is the same as (1*10%)+(2*10%)+(3*10%)+(4*10%). My way is easier.

Hello Richard.

I'm writing to you to ask you if you have any suggestions on how to add another field to the iform which would be  to be fed by another table which holds my prices for items which can we put onto the form and work out my cost all materials as I make pay invoice for a job
 Alex Hedley 10 months ago If it's a single field you can use a DLOOKUP. If you have 2 prices in the product table, purchase and selling you could just add both to the query and show both.

I cant enter enter new records in my order detail query
SQL:
SELECT OrderDetailT.OrderDetailID, ProductT.ProductName, ProductT.ProductPrice, OrderDetailT.Quantity, [ProductPrice]*[Quantity] AS PriceExTax, IIf([IsTaxble],Round([PriceExTax]*0.2,2),0) AS TaxPrice, [PriceExTax]+[TaxPrice] AS PriceInclTax
 Richard Rost 12 months ago Not surprised. A lot of the time when you create a query with a JOIN it becomes non-updateable. Use a form with a subform.
 Abraham Breuer 12 months ago but the form will also show my orders and not allow me to edithow can I make it editable?
