Try It Out: Add Currency Fields

To keep track of a position's salary range, we need to add two currency fields: Min Pay and Max Pay. Note that unlike some fields, once we define these as currency fields, we won't be able to change them to any other type.

Defining a currency field is almost identical to defining a text field, with a few slight differences.
  • The Length of a currency field actually corresponds to the number of digits to the left of the decimal point. An additional Decimal Places field handles the number of digits that should be displayed to the right.
  • In the Details page of the wizard, a new checkbox called Required is displayed. We can select this option if we want to force our users to enter a value for this field when creating a new position.
Everything else should be familiar to you, so go ahead and use the custom field wizard to define the following fields:
Table 1. Position Object Currency Fields
Data Type Field Label Length Decimal Places Required Default Value
Currency Min Pay 7 2 Leave unchecked Leave unspecified
Currency Max Pay 7 2 Leave unchecked Leave unspecified
