Dear Jörg,
thanks a lot for your explanation!
The reason for my request is that we currently use the RFC_REMOTE_PIPE to execute some OS commands for creating, deleting and moving trigger files (for a prpcess chain) on OS level which should contain the timestamp.
Now we want to substitute the RFC_REMOTE_PIPE function and thats why I am searching for another solution to delet, create or move this little file and I tried to use OS commands in SM69 because I wanted to avoid abap programming.
So basically you helped already because now i know that it will not work to use '>' in SM69.
I will have a look at your proposal with using 'get time', open dataset,......but I am not good in ABAP.
If you know any other workaround your advice is really welcome.
Anyway.....many thanks for your input so far.
