How to start picking files from source folder once a particular file is placed?

[Former Member]

Hello Experts,

My requirement is like ECC is creating multiple file and Client wants that PI should start picking the file only once a final file like'.done' file is there.

Can any one help me on this that how can we proceed with this requirement?

I have gone through following two options:

Option 1: "Msecs to Wait Before Modification Check".

Option 2: Trigger file logic through checking 'Additional File(s)' check box in Sender Communication Channel.

Hi Pradeep,

you can use the trigger file option. Please check the below wiki question 4

Hi Harish,

I have gone through this blog but it couldn't help if the number of files are more than one with different name.

Hi Pradeep,

After you place the done file you can start the channel externally in the abap program itself, please check the below blog for reference.

Hi Praveen,

This option looks pretty good to me.

I will surely check this by tomorrow and will update you .

Hi Pradeep,

If you want to pick number of files with different name you can use advanced file selection option

using that you can able to pick the files.

Hi Praveen,

I have gone through this blog and created the report. But while calling method

*Get http response from server

call method CLIENT->RECEIVE

   exceptions

     HTTP_COMMUNICATION_FAILURE = 1

     HTTP_INVALID_STATE         = 2

     HTTP_PROCESSING_FAILED     = 3

     others                     = 4.

Sy-subrc value is coming as '1' and giving following error 'HTTPIO_PLG_CANCELED'.

Can you tell me what can be wrong in this.

Hi Subhani,

Its not about picking multiple file.

We have to start picking the file only once Job is completed in ECC and ECC will place '.done' file.

Once '.done' file is there PI needs to start picking the file and process them.

Hi Pradeep,

Actual one is this

"Start comm channel
"v_url = '/AdapterFramework/ChannelAdminServlet?party=*&service=*&channel=Test_CommChannel_ExtCtrl&action=start'. 

"Stop comm channel
"v_url = '/AdapterFramework/ChannelAdminServlet?party=*&service=*&channel=Test_CommChannel_ExtCtrl&action=stop'. 

But you have written this.

"Start comm channel

v_url = 'http(s):XXX.XX.XXX.XXX:XXXXX/AdapterFramework/ChannelAdminServlet?party=*&service=*&channel=CC_File_Merch_Recv&action=start'.

"Stop comm channel

"v_url = '/AdapterFramework/ChannelAdminServlet?party=*&service=*&channel=Test_CommChannel_ExtCtrl&action=stop'.

Check it onece.

Hi Pradeep,

I got your point,earlier i thought issue is related to multiple files.

Thanks Guys..

This problem is resolved. Now I am calling the suggested Report from ECC to start the Communication Channel externally once Job is completed in ECC.

Regards,

Pradeep

[Former Member]

Hi Pradeep,

So is it a batch job which is creating these multiple files and placing in the directory? You can set the Polling interval of the channel or set up Availability time planning for this channel to pick up file in a time interval when the job ends or based on the logic in place.

Hello Sriram,

Yes its a Batch job and above option could not suffice as we have time constrain and needs to start picking the files as soon as the '.done' file is placed

[Former Member]

Hi Pradeep,

Agree, so whats the frequency of the job?

Regards,

Sriram

[Former Member]

Hi Sriram,

This is a daily job and we have to complete the job in less than 2 hour of which ECC part is taking around 1.5 hours for data extraction.

Pradeep

[Former Member]

Hi Pradeep,

If its a daily job, then you set up ATP as per the end time of the job with some buffer and set an external control to start the channels and stop it post that.

Try and see if it works and satisifies ur requirement. If i have not understood the requirement correctly please do let me know so that i can help further

Regards,

Sriram

[Former Member]

Hi Sriram,

Can you please elaborate the external control thing to start or stop the channel.

Regards,

Pradeep

[Former Member]

Hi Pradeep,

Please check the below link.

Controlling a Communication Channel Externally - Process Integration Monitoring - SAP Library

External control may not even be required if you know that the predefined job finishes at a paritcular time. You may just start the channel based on the job end time with a buffer..
