Receiving Files from FTP Server

Perform the following steps after creating the FTP connection to receive files from the FTP server using Sigma Studio:

Right-click the created FTP server connection and select the Create Data Source option.

Refer FTP – Connectors for more information on creating a FTP connection.

The Create Request page appears.
Enter a unique data source name in the Data Source Name field, e.g. FTP_DS.
Select the Get File option in Request Type to receive the requested file from the FTP server.

You cannot make use of the FTP data source, configured with the Get File Request Type, to create a report in Sigma Studio.
Provide the appropriate file path on the FTP server to which the files need to be transferred obtained from the server in Relative Path on Server field.
Provide the appropriate local file path from which the files need to be transferred obtained from your local drive in Local File Path field.
Provide the file name that needs to be obtained in File Name field.
You can receive the files of the following formats from the FTP server:
- CSV
- XLS
- PDF
- DOCX
- TXT
- HTML
- XML
Click Save to save the FTP data source.

A success message for creating the data source appears as shown in the following screenshot:
Click Ok.

In order to trigger the FTP service connection, the CT platform's server-side API, CT.ftp must be used while passing the ExecutionContext action in a Java Handler class. Refer the following sample code snippet for better understanding on the triggering process:

Here, on the following sample code snippet a new ExecutionContext action is created within which a map (HashMap) is built. The FTP datasource ID is passed as the input to activate the connection request within which the CT.ftp API is passed to trigger the process.

ExecutionContext ec = new ExecutionContext();
	Map inputParams1 = new HashMap();
	inputParams1.put("DATA_SRC_ID","FTP_DS");  // Here, FTP_DS refers to the Datasource ID.
	ec.setInitialRequestData(inputParams1);
	try {
		CT.ftp(ec);
	}
	catch(Exception e){	
	}
