Defining parallel activities
The Fabasoft Folio Workflow Engine allows you to define processes that are comprised of parallel activities and control elements.
Defining a block of parallel activities
Syntax |
parallel {
// Activity definitions or control elements
...
} |
The parallel keyword is used to define blocks of parallel activities. parallel blocks can be nested within a process block, within control element blocks or within other parallel blocks.
Example |
processes APPDUCXSAMPLE@200.200
{
import COOSYSTEM@1.1;
import COOWF@1.1; process ApproveOrderWF {
parallel {
activity {
actor {
pos = Clerk;
orgunit = OrderProcessing;
}
step ApproveOrder required leave {
execute = ApproveOrder;
}
step DenyApproval required leave {
execute = DenyOrderApproval;
}
}
activity {
actor {
pos = DeptManager;
orgunit = OrderProcessing;
}
step ApproveOrder required leave {
execute = ApproveOrder;
}
step DenyApproval required leave {
execute = DenyOrderApproval;
}
}
}
}
} |
A process can be split at any time using a parallel block. The default behavior when joining parallel process paths is that all parallel activities must be completed before the workflow continues with the next non-parallel activity in the process.
Defining activity sequences within a parallel block
Syntax |
parallel {
// Activity definitions or control elements
...
sequence {
// Activity definitions or control elements
...
}
// Activity definitions or control elements
...
} |
The sequence keyword is used to define a sequence of activities within a parallel block. It must be followed by a block defining the sequence of activity definitions and control elements within a path of a parallel block. A sequence block can also contain another parallel block for splitting the current process path.

processes APPDUCXSAMPLE@200.200
{
import COOSYSTEM@1.1;
import COOWF@1.1; process ApproveOrderWF {
parallel {
activity {
actor {
pos = Clerk;
orgunit = OrderProcessing;
}
step ApproveOrder required leave {
execute = ApproveOrder;
}
step DenyApproval required leave {
execute = DenyOrderApproval;
}
}
sequence {
activity {
actor {
pos = DeptSecretary;
orgunit = OrderProcessing;
}
step ApproveOrder required leave {
execute = ApproveOrder;
}
step DenyApproval required leave {
execute = DenyOrderApproval;
}
}
if (object.preapproved) {
activity {
actor {
pos = DeptManager;
orgunit = OrderProcessing;
}
step ApproveOrder required leave {
execute = ApproveOrder;
}
step DenyApproval required leave {
execute = DenyOrderApproval;
}
}
}
}
}
}
