SAP CPI: Not able to pick done file

[MohitRelwani]

Using Sender SFTP, I am trying to pick the Main file based on Read lock strategy as Completion file.

Main file Naming Format: abc.TXT
Done/completion File Format: abc_CMPL.TXT

What should be the format of Done file Naming. Seems it only supports when extension is .done.

Please suggest

Hello Mohit, 

The format of done file should be ${file:name}.done

Example : hello.txt is the file to be consumed, hello.txt.done is the associated .done-file.

Please check the below link for more details :

Building on Punith's correct answer: The SFTP adapter specifically uses the pattern ${file:name}.done. Here, ${file:name} is a dynamic expression within SAP Integration Suite that automatically resolves to the actual name of the source file being processed. So, if the adapter picks up abc.TXT, this expression evaluates to abc.TXT.done. The adapter waits for this exact .done file as confirmation that abc.TXT has been completely written to the server. This prevents the integration flow from reading an incomplete file during transfer. Regards, F.

Backend is already generating abc_CMP.TXT as the completion indicator file. This is already a working solution in PO and we are migration to BTP IS. Seems like we need to get this changed from backend to make it compatible with BTP IS?

Hello Mohit, Yes that is correct, Ask the backend Team to change the filename to achieve this in SAP CI.
