SAP HCP-IS [ SAP HCI ] How to set Target Filename and Directory dynamically in SFTP Adapter

Introduction:

Being SAP PI consultant we all know how Dynamic Configuration works with File adapter and how to set the target filename dynamically.Now we have started with SAP HCI era and need to find how to achieve the same.Here is the blog which showcase the same by using Apache Camel File Processing Parameters in Content Modifier.

Lets discuss various use cases in detail.

1. How to set Source File Name to Target File Name

Create integration Project like below

Step 2: Configure Content Modifier to set the source file name to target file name.

CamelFileName: Parameters which holds File Name in Apache Camel Framework (Upon which SAP HCI-PI is built on).

file:onlyname.noext: Holds the filename text without considering Extension.


There are also other parameters which can utilized( See the below table )

 

Expression Returns
file:name HCI\InputFile.xml
file:name.ext xml
file:name.noext HCI\InputFile
file:onlyname InputFile.xml
file:onlyname.noext InputFile
file:ext xml

 

Step 3:Configure the receiver SFTP Channel like below

Go ahead and deploy the integration project.Now you will have a file in the target SFTP folder with filename same as source filename.


2. How to set target filename dynamically based on key field from incoming message.

Configuration: Create integration project similar to Use Case 1 and repeat the Steps 1 and 3 .


Step 2: Content Modifier configuration

Below are parameters used in the content modifier.

${date:now:yyyyMMdd}: Captures current date of file processing.

${header.User}, ${header.Group}: Captures values from incoming file.


Go ahead and deploy the integration project.Now you will have a file in the target SFTP folder with dynamic filename based on input file.


3. How to set target filename and target folder structure directly (By leaving the Directory and FileName Blank)

Configuration: Create integration project similar to Use Case 1 and repeat the Step1


Step2:

${date:now:yyyyMMdd}: Captures current date of file processing.

${header.RecordCount}: Holds number of records in the input file.

${header.User}, ${header.Group}: Captures values from incoming file.


Step3:

Go ahead and deploy the integration project.Now you will have a file in the target SFTP server with dynamic filename based on input file and in the target folder which is set in the content modifier step.


Conclusion:

Hope this blog helped beginners to dynamically set filename and target folder in SAP HCI using Content Modifier.

      Hi Sriprasad

      Thanks for sharing this. It is indeed useful reference especially as PI/PO developers get themselves familiar with Apache Camel.

      May I suggest that you include a link to the appropriate Apache Camel resource which lists the various parameter reference available?

      Regards

      Hi Aditya,

      Your expression is trying to capture the current date of file processing so if i am right first you need to capture the last modification date of the file and then try to compare it with current date which could be done with the help of any scripting code.

       

      In order to capture the last modification date a file then modify your expression with help of below :

       

      https://docs.oracle.com/javase/8/docs/api/java/text/SimpleDateFormat.html

       

      Also try to match your consumer folder date format something like MM/dd/yyyy HH:mm and if any luck works let me know the result.

      Cheers!

      Hi Sriprasad,

      I need to pick the latest file from SFTP server. My file name looks like ABC-2019-05-21-042724.csv

      I am using the SFTP Sender adapter and giving the file name as ABC-${date:now:yyyy-MM-dd}-*.csv

      But it is not picking up the file. Could you please help in how to achieve this.

      Note: We don't have archiving

      Regards,

      Hi Sriprasad,

       

      Hope you are doing good.

       

      I have a requirement to read the sftp sender directory details  dynamically and pass into mapping as an input for one of the filed in CPI.

      could you please guide me the camel expression to fetch the folder details dynamically from the source SFTP.

       

      Thanks in advance!

      Hi Shivaram,

      For AS2 sender adapter CamelFileName added with value "${file:onlyname}" to get the same file name but it is not working as expected.

      We have AS2 to SFTP pass through scenario and need the same file name store on SFTP server which sent by partner and at partner side AS2 file name also configured.

      Note that Partner is sending .CSV files.

      Could you please help me on this.

       

      Thanks,

      Khaja S.

      Hi Sriprasad,

      Thanks for the excellent blog.

      I have a requirement where I am receiving a file from an SFTP resource and need to dynamically modify the name of the file inside CPI.

      For example, if the name of the input file is Test123, I would like to dynamically change the name of the input file inside CPI as : 'Test-123'. Could you let me know how the same can be done.

      Thanks,

      Sushanth

      HI All,

       

      I tried to implement this but not getting the value from the Sender or receiver xml structure.

      not sure if CPI has updated the logic in 4 years,that is why its not picking the value ?

      Hi Sriprasad,

      This is indeed a excellent blog with good explanation.

      I have one query related to the directory in Method:3 , Does the Same Parameter "CamelFilename" is used for fetching directory also during runtime!!?

      I'm mainly worried how to tell the system which is filename and which is directory if we are giving both in same parameter. Do we have certain character to segregate both like Underscore etc?

      Take your Example itself , We have CamelFilename = "/HCI/Inbound/Output_${header.User}_${header.Group}_${header.RecordCount}_${date:now:yyyyMM}.xml"

      Here , Could you tell me on what basis CPI is segrating this value into Directory and File Name please?

      Thanks,

      Dinesh
