SAP PI - File To Proxy - Sender Channel Start And Stop

[vishnu_pallamreddy]

Hi All,

I have a requirement where I have to start and stop the channel by processing button/event in ECC.

My scenario is File to Proxy.

If an event or Button processed in ECC then Sender SFTP channel has to start and after processing all files to Proxy from SFTP the should stop.

Any one please suggest me the procedure.

Any abap code for Start and Stop the channel.?

Thanks In Advance,

Vishnu.

Hi Raghu,

I have one doubt here.

After 10 th file processing the channel will stop right?

Hello Vishnu,

It wont stop processing,It will keep on polling until you stop it.

Hi Vishnu,

• First write the files from ABAP program
• After finish writing the files in application server then start the SFTP channel from ABAP program.
• After 30 minutes you stop the channel from ABAP program.
• You create a background job with two steps, first step is to write the files in application server, the second step put the program which start the channel.
• After 30 minutes you can schedule the program to stop the channel.

Praveen.

Ok Raghu.

But I need to stop after processing of all files automatically.

we don't know the number of files generated every day.

after processing of last file it automatically stop the sender channel.

Hello Vishnu,

If the number of files are not fixed,how you decide the last file?.

It should be based on either time or count or any content.

You need to re-write the code accordingly.

Hi Raghu,

I have the same question.
I am checking with Client.

Thank You.

Hi Raghu,

• No need to know the number of files up front.
• We are going to create the background job with two steps.
• First step is the program which create the files in the application server, so the program will create n number of files not need to be fixed.
• After the first program finished successfully then second step will be executed which is the program to start the channel, so when second program runs at that time all the files will be there in the directory.
• After 30 minutes we can schedule other program to stop the channel.

Regards,

Praveen.

Hello Praveen,

Seems to be a nice idea.

But if more files are created and if the SAP SFTP is not able to process that in the stipulated 30 mins will it not be a problem?

Guess polling interval also should be kept low.

Hi Raghu,

We can adjust the second background job based on the requirement, they can change from 30 minutes to one hour or two hours, i just gave the example.

Hi Praveen/Raghu,

Is there any way to STOP file communication channel automatically if file sever contains no files(means  is there any module configuration parameters available in PI to stop communication channel automatically if server doesn't contain any file ).

Thank you,

Narsaiah,

Existence of the file can be checked when the channel is active only , so there is no standard way to do this , however channels can be controlled externally .

Like the Sender application can call the http url whenever it places a file in the folder so that PI channel gets started and the file is picked .
