[SAP CPI] – HOW TO USE DYNAMIC CONFIGURE FOR SFTP RECEIVER ADAPTER

Hi guys, in this article I want to discuss about How to use dynamic config for SFTP receiver adapter. As you know, in scenario integration between CPI and SFTP, we have to set hardcode value of SFTP as address, directory, filename, credential… in integration flow with SFTP receiver. For example

In many cases, we have to parameter all of this variable. How to do that ?

Actually, We can use externalize parameter. In newest release, CPI support type DYNAMIC for Proxy Type and Authentication dropdown. If choose this value, configuration will get value from property as

Attribute	SAP property	Type	Values
Proxy Type	SAP_FtpProxyType	String	internet/onPremise
Authentication	SAP_FtpAuthMethod	String	key/user/dual
Timeout	SAP_FtpTimeout	int	Values of type integer
Max. Reconnect Attempts	SAP_FtpMaxReconnect	int	Values of type integer
Reconnect Delay	SAP_FtpMaxReconDelay	int	Values of type integer
Automatically Disconnect	SAP_FtpDisconnect	boolean, string	true/false
Change Directories Stepwise	SAP_FtpStepwise	boolean, string	true/false
Create Directories	SAP_FtpCreateDir	boolean, string	true/false
Use Fast Exists Check	SAP_FtpFastExistsCheck	boolean, string	true/false
Use Fast Exists Check	SAP_FtpAfterProc	String	Overwrite/Append/Fail/Ignore
Flatten Filenames	SAP_FtpFlattenFileName	boolean, string	true/false

Configuration dynamic for SFTP Address

• Add Content Modifier component into integration flow
• Add header as

Name	Source Type	Source value	Data Type
address	expression	{{address}}	java.lang.String
credentialName	expression	{{credentialName}}	java.lang.String
userName	expression	{{userName}}	java.lang.String

• Add property for content modifier as

Name	Source Type	Source value	Data Type
SAP_FtpProxyType	expression	{{sftpProxy}}	java.lang.String
SAP_FtpAuthMethod	expression	{{sftpUser}}	java.lang.String

If you select DYNAMIC for dropdown proxy type and Credential in iFlow, you have to define propery SAP_FrpProxyType and SAP_FtpAuthMothod. If no, you will take error.

Test configuration

Choose Artifact and click configuration to set value for parameters

Summary

In this article, I discuss about How to configuration for SFTP dynamic. I also talk about Externalize Parameter to set value for parameter from artifact configuration. Thanks for your reading and any question, kindly leave your comment below this article.
