Configuring your FTP server and other SAP-related tasks

SAP System Administrators can configure their File Transfer Protocol (FTP) server in two locations.

Before you begin

Ensure that you have set up custom ABAP function modules installed in the SAP system. The archive with transport files feature is available in the installation folder of Talend Studio.
Ensure that you have an SAP Non-Dialog User with proper authorizations to execute the ABAP function modules and to read from the required application tables that you are using.
Ensure that you have installed the current version of the SAPJco library. You can download the package through the SAP marketplace.
Set your firewalls accordingly:
- Open the Port for the RFC communication. Example: 33xx, xx-SAP Instance Number[00..99])
- Open the Port for the FTP communication

Procedure

Option 1: Create your FTP server on the same server as the SAP system
1. Create a folder where you can store batch files temporarily created during the table extraction process.
  
  The SAP system must have full access to this newly created folder. Ensure that you have the <sid>adm user on Linux or SAPService<sid> user on Windows to have access to all SAP-related local resources.
2. Install the FTP service.
3. Create a user account that you can use with the FTP client. You need this account to connect to the Talend Studio component.
4. Define proper authorizations for the FTP user. Ensure that this user only has access to the newly created folder used for the batch file transfer with execute, read, and delete* operations.
Option 2: Create your FTP server on a separate server
1. Create a folder where you can store batch files temporarily created during the table extraction process.
  
  The SAP system must have full access to this newly created folder. Ensure that you have the <sid>adm user on Linux or SAPService<sid> user on Windows to have access to all SAP-related local resources.
2. Install a Network File Service (NFS) on the SAP server.
  The folder you have previously created in step 2.a is released through the NFS for the FTP server.
3. Install the FTP service on a separate server.
4. Install a Network File Service (NFS) client on the FTP server. The folder you have previously created in step 2.a is mounted and accessible through FTP.
5. Create a user account that you can use with the FTP client. You need this account to connect to the Talend Studio component.
6. Define proper authorizations for the FTP user. Ensure that this user only has access to the newly created folder used for the batch file transfer with execute, read, and delete* operations.
Information noteRemember: * All batch files are deleted after a successful transfer to Talend Studio.
Option 3: If the installed transport archive considers stricter security policies, it requires additional customizing activities as below.

The temporary path for the batch-files can only be defined on the SAP side. For the setup, use the transaction file and define a logical path as well as a logical filename as follows:
1. Set the logical path: /CMT/TLND_PATH.
2. Assign a physical path to the logical path.
  
  Information noteNote: The configuration required for the physical path remains.
3. Define a logical filename: /CMT/TLND_FILE.
4. Assign the logical filename to the logical path.
