Workflows have been migrated to Flows
From Version 11.1, new Flows have been introduced as a replacement for Workflows, in line with Salesforce’s policies. We recommend using the Flows for all new implementations.
Equivalent Flows are available with the same names as the workflows (prefixed with “Payments2Us”).
These invoices are sent by Workflow. You/your system administrator can disable this by:
- Click on Setup cog (top right), then select "Setup"
- Quick Find/search "Workflow Rules" and click into the "Workflow Rule" menu item
- Locate Workflow rule "Send Payment Schedule Invoice" that is against the "Payment Txn" object and press the "Disable" link to de-activate.
