See the Administer Help Center for information about how to configure the B2B connections created in XTT AWS:
To configure B2B connections Application Administrators can create and view B2B connections, which is a configured B2B gateway account that is uniquely identified by a B2B connection name using Applicability Statement 2 (AS2) protocols, Secure File Transfer Protocol (SFTP) and Simple Mail Transfer Protocol (SMTP) in the XTT app. After creating a B2B connection, System Administrators can configure a B2B connection in the Administration app so the appropriate Link Identifier, SAP Configuration, and EDI Configuration settings can be used for the app or network. System Administrators can add X12, EDIFACT, or IDoc location settings information to complete adding a B2B connection. System Administrators must configure an inbound or outbound message prior to adding the connection type information.
Assign Extensible TraceLink Transfer rolesSee the Administer Help Center for information about how to assign Extensible TraceLink Transfer roles to users.
Roles Application Administrator – Allows users to create and update B2B connections and view B2B messages in the Extensible TraceLink Transfer app. The Application Administrator in the Administration app can add users and assign their roles. Member - Standard Access – Allows users to view existing B2B connections and the exchanged B2B messages. Configurations for an SFTP connection Create a public and private key using PuTTYgenOpen PuttyGen and select the RSA key type and set the number of bits to 4096.
Copy the generated public key or select Save public key button.
Ensure the public key does not contain line feeds or carriage returns.
Enter a password in the Key passphrase field and confirm the updates.
Select Save private key button.
The generated public key is required while adding an SFTP connection.
TipsThe recommended naming format for the public key is -_Public_Key.txt (e.g., USPT1-VAL_Public_Key.txt)
The recommended naming format for the private key is -_Private_Key.ppk Exchange files using FileZila or WinSCP See the information required to exchange documents using FileZila Open Site Manager and select New Site on Site Manager.
