There are some unique complexities introduced when we introduce multiple units of measure and alternate currencies. Additionally, when we try to return a list of prices in a quantity range, we need to meld the sale price at each quantity break to the standard price and return the appropriate table information.
Once the system has selected a Price Matrix record to use, it will pull out the proper quantity break row and calculate the price. If no price matrix record is found, the Product List Price will be used.
The following steps describe the calculation logic for the Generic Price Calculator. It will be followed by ERP-specific adjustments to that.
The basic flow will be:
- Gather all appropriate records from the db
- Filter out the ones that do not matter
- Organize the records from most specific to most general
- Find the right record to use
- Calculate the prices
- Compare to sales price
- Return results
When we indicate most specific to most general, this also applies to warehouse and unit of measure.
|Price Basis||Adjustment Type||Basis Amount||Entered Amount||Calculation||Calculated Price|
|List||Amount||125||-10||List Price + Amount||115.00|
|List||Percent||125||-10||List Price * (1 + Percent)||112.50|
|Cost||Amount||75||30||Cost + Amount||105.00|
|Cost||Percent||75||30||Cost * (1 + Percent)||97.50|
|Margin||Amount||75||30||Cost + Amount||105.00|
|Markup||Amount||75||30||Cost + Amount||105.00|
|Markup||Percent||75||30||Cost * (1 + Percent)||97.50|
Each individual quantity break line stands on its own relative to the calculations.
