Creating Custom FieldsType field nameType a colon : after the field name

Type in what will appear in the fieldExample: Target Week of Supply:8 You can identify a custom field by the colon or by ablank table cell in the query design grid

Basic Formula in Access: Field name Mathematical operator

Field name Each table name and each field name is surrounded by

square brackets [ ] An exclamation point separates the table and field

names Example: Weeks of Supply:[Sales Data]![Current

Inventory Units]/[Sales Data]![Unit Sales LW]

Basic Formula in Access: Anything before the exclamation point is a table name. Brackets indicate that a mathematical calculation is to be

performed. Math operators are just like Excel. You cant apply a mathematical operation to specific cells they

are applied to the entire field. Use field names (like cell addresses in Excel) to construct

formulas rather than constants. Use constants when necessary for things like months in a year,

minutes in a hour, etc. Example: Days of Supply: [Sales Data]![Current Inventory

Units]/([Sales Data]![Unit Sales LW]/7)

Basic IIF FunctionImmediate IF (works like IF function in Excel)

expression = logical testUsually a field name followed by a comparison operator or textenclosed in quotation marks

Truepart = defines the output of the function if logicaltest is trueFalsepart = defines the output of the function if thelogical test is false

Financial FunctionsFuture value (FV)

Calculates the future value of an annuity

Rate, nper, pmt, pv, typePayment (pmt)

Calculates the payment given a constant interest rateand constant payments

Rate, nper, pv, fv, typeNecessary to adjust so units are equal just like inExcel
