What happen when an error occurs during Snapshot-Refresh?

Question

Hi,
I would like to know what happens, when an error occurs
during a refresh (COMPLETE-REFRESH) of a snapshot?
Is there a possibility for exception-handling??
During a complete refresh the data in the snapshot will be deleted an the requested new from the master-side. Now when
an error occurs during the refresh what happens with the "old" data of the snapshot??? Will it be lost?
Thanxx

Each thread has its own error state. To get the results for a thread (including error result), you need to have a wait step which waits for it. If a thread has an error and you wait for it, you will get the error at the wait step that waits for it.
If your main thread has an error and you want some worker thread to exit, you should add code to the cleanup of your main thread's sequence which signals the worker thread to exit (you should already have some sort of mechanism for signaling the worker thread to exit (there are many ways to do this, for example, a boolean variable passed by reference to the new thread's sequence, or a TestStand notification).
If your main thread is getting an error, but is stuck inside a step, that problem is probably specific to something your code is doing, that is not the normal behavior of TestStand. You will need to provide more details or an example sequence in order for us to better understand what is happening.
Hope this helps,
