Hi there
Markups can be applied within the trade agreement (pre-emptively) during creation, using the Adjustment functionality.
From the trade agreement journal:
1. Click the Adjustment button > Adjustment
2. Click on the Price field drop down
3. Select Cost price or Current, depending on what you want to make the calculation based on
4. Enter your desired % or amount, that you want the system to calculate the adjustment by
5. Click okay
6. The system will then automatically update the Amount in currency on ALL trade agreement lines that exist within the journal
In your scenario, you must first create the required lines, with your desired combination of Customer group / Item. The adjustment functionality can then be used to achieve the rest.
As a second option, the Excel editor could also be used to apply logic / formula etc to calculate the prices based on your requirement.
As a third option, functionality also exists in the Retail module to manage prices (See category price rules)
