Conditional get of files via XI 3.0

Hi all,

I have a scenario where a third-party system will create seven files that should be picked up and processed by XI. The process will in brief look like this. First a start. tmp file is created then the seven data files are created and then a finished.tmp file is created.

What I need to do is to first check, do we have a finished.tmp file. If so I can go ahead and process the seven data files. But if the finished.tmp file does not exist I do not want to start the processing because then this indicates that something is not OK. This means that I only want to process if all files are present otherwise stop.

Anyone has an idea how I would go about to accomplish this in XI 3.0?

Regards,

Fred
