Why does startsap only start one of my instances?

Hi,

During my last maint I noticed that the startsap command only started one of my dialog instances D30, but not the other one D10. However, if I ran "startsap D10" is started without problems.

Any idea of what could be wrong? What do I need to change to make it start both my instances with the startsap command?

Thanks in advance!
