Hi Hemalatha,
a decision activity decides its post way by the return boolean inside the decision activity. Here an example:
if ( 1 > 0 )
{
return true; //Now follows the way with the green arrow
}
else
{
return false; // Now follows the way with the red arrow
}
So simply use the output of your "Create a computer i..:" workflow as input for your decision activity and build a decision inside which returns true or false even what is in your case correct.
Regards,
Chris
