Create a screen much like the Edit Project Expiration Dates screen under Manage, Application Management. This way the Trade Amounts can be updated if necessary based on the specific Customer Code entered and allow the user to select as many projects as they want at one time and affect the Trade entered into the project. Currently the user has to not only update the Trade under the customer level but also decide which projects should receive the updated Trade discount and which ones should retain the old Trade Discount or old pricing. Or use the Calculate Pricing Changes Tab to include Project Trades.
