Which transaction message types should I configure in TCS before I can create rules in TRS?

When creating a new connection (DEMS mapping) in the Tazama Connection Studio (TCS), use pacs.008 or pacs.002 as the transaction message type. These are the standard ISO 20022 message types that Tazama's core pipeline natively supports. Once the TCS connection is created and approved from the approver context, the transaction type will appear in the Transaction Type Selection dropdown in the Tazama Rule Studio (TRS). If you set up pacs.004 or a custom type in TCS but cannot find test data in the TRS Rule Library, confirm with the team that corresponding sample data exists for your transaction type.
