Use the Purchase scale prices for external operation form to define pricing scales for the selected supplier. Examples of scale prices are:
Scale prices that apply to specific suppliers
Scale prices that apply during a particular period
If the Use standard values option is selected on the calculation line for external operations, the purchase price of an external operation in a purchase requirement or on a purchase line is based on a pricing scale that may apply. If no valid pricing scale is found, the price is copied from the External operations form. If a pricing scale has been defined, the price specified in the pricing scale is used if in the purchase requirement or on the purchase line:
The date falls in the period defined for the pricing scale (Start date and End date fields)
The quantity is within the pricing scale range (the quantity is greater than or equal to the Quantity from value defined in the pricing scale)
The currency matches the currency defined in the pricing scale.
If you are not using the Use standard values option, the purchase price of an external operation in a purchase requirement or on a purchase line is copied from the calculation line for external operations. In that case, any scale prices will be ignored.
The pricing scale is valid from the start date. If you fill in an end date, you are defining a period during which the pricing scale is in effect, such as a calendar year. If you leave the End date field empty, the pricing scale will remain valid from the start date specified.
Specify the lower limit of the quantity range to which the price applies, for example $ 3 per 5 m2, and $ 2.75 per m2 for 10 m2 or more. The quantity is the total Quantity * Units per piece as defined on the calculation line for external operations.
The script you specify is executed when you start the Get price process if the pricing scale is used in the search path to determine the purchase price of the external operation.
