Asset Line Item Filter Callback Class
Implement the Asset Line Item Filter Callback interface if you are enabling Wallet Manager Flow. This callback interface filters all the regular asset line items and displays only the active wallet asset line items on the Installed Products pages. All wallets with asset end date older than the system date are considered as expired and are filtered out from the Installed Products page.
To add the custom class
- Go to Setup > App Setup > Develop > Apex Classes.
- Click New.
Enter the sample callback class code.
Click Save.
This is just a sample callback class. You may change the code per your requirements.
In order to implement the interface, prefix it with Apttus_Billing.CustomClass.<Interface Name>.
