SGEN Exclude all include and non -existent programs issue

Hello,

I need help regarding t code SGEN.

When we tried to execute the transaction it got stuck at the
point " Exclude all include and non -existent programs " and gets
terminated with a TIME_OUT error

We have a feeling that
it's something to do with SQL Server buffer size but not sure what's the exact cause
of the issue.

Thanks,

Aju Abraham
