Automatic VSR trigger

Hi all,

the following is my situation.

With regard to warranty claims processing I had made the setting in the action control that action A006 has to run automatically. Now while creating the warranty claim the starting status is null while the target status is say "ZFIRST" when A006 is run. Now when does this action get triggered? When I save the WC? Or even as I enter the screen with null status? I have written a VSR validation which is getting triggered and I get an error message successfully in the VSR log when the action is manually run. But automatic trigger of the action is not happening because I don't see an error in the VSR log neither upon saving nor while entering the screen. Any clue?

regards

Bala
