Wait for a file and start execute a scenario process

Question

What is the best way to achive: Wait for a file and then once the file in droped...execute a scenario process.
Sample scenario:
- Admin user ftp the file to a target directory on Unix (export/home/odi/input/files)
- A scheduled scenario package will be running/scheduled daily
- In the above scenario, The first step is to have one OdiFileWait (with options: Dir:/export/home/odi/input/files, File: xxxxx.txt,wait time and loop over..etc)
/* But for some reason OdiFileWait is not waiting/checking for the file presence define in the option. It seems to run immediately without checking the presence of the file and passing it to run the second step) */
- The second step is the "OdiStartScen" (This will run an interface generated scenario) and since the file doesn't exist as a source to load that this interface uses...its fails.
What's the common practice to accomplish this? Appreciate your feedbacks…
Thank you

Update:
I increased the timeout and Pollint setting in OdiFileWait option and its working fine now.
When the file exists (or) ftp within the timeout the process goes to next step (OK). But, say the file doesn't exists and the timeout finished...how do i set a KO to OdiFileWait and stop/complete by existing at that step itself with out failure.
