Try using Pause/Resume script to pause the script for a few seconds immediately after the go to field step.
Phil, thanks a lot for the hint. Unfortunately it does'nt change anything. As soon as there is another step after the "go to field" command the script does not work (I added it below). So in this case, I receive a pdf of my table instead of the records specified in the snapshot link file. Same behavior when I run the script in the debugger. I can see that is marks the right field with a blue frame - but it does not open the new window. As soon as I delete the last two lines, it opens the correct window with the records from the snapshot link very nicely.
Is there a different approach to store information about printing/pdf in a table that need to be accessed by a script?
It's an interesting question and this looks like something to report as a bug over in Report an Issue.
What happens if you pause the script indefinitely?
Another way to pause the script is to use Install OnTimer script to perform the follow on "Save as PDF" part of your script so you might also try that option.
