Only one document will open after excecuting the report

Hi everyone,

I am now working a report and this report will create one doc.

But if I run this report on some models(for exmaple 4 models) at the same time, will 4 doc. created, but only one of them will automatically open. However, I hope all this 4 doc. can be automatically shown.

How can I solve this problem?

Thanks in advance.
