Before we continue, let's explore this editor in greater detail. An assignment is composed
of three columns:
From Object
,
Assignment Type
, and either
To Object
or
To Value
.
For input assignments—which means the value we want to assign to one of the input vari-
ables of the task—we have to decide whether we want to assign a fixed value to it or if we
want to map a process variable to it.
In the case of a fixed value, in the
From Object
column, we have to select the input vari-
able that we want to assign from the drop-down list that contains all of the data input and
output variables and process variables. The
Assignment Type
value required to assign a
fixed value to a variable is
is equal to
. The third part of the assignment when we are
assigning fixed values to an input variable is defined in the
To Value
column, where we
have to enter the value we want to assign to the input variable. If what we want to do is
map an existing process variable into one of the input variables of the task, we need to se-
lect the process variable first in the
From Object
column. Then, we have to select
is
mapped to
for the next column, and finally, we have to select the task's input variable
that we want to be assigned in the
To Object
column.
For output assignments, in the
From Object
column, we have to select the output variable
we want as the source of the assignation. In the
Assignment Type
column,
is mapped
to
is the only valid value, as we can't map an output variable to a fixed value. Because
