Guidelines for using input parameters in taskflows
Guidelines for using input parameters in taskflows
Use the following guidelines when you use input parameters in a taskflow:
Use the Data Task step to override input parameters. However, in advanced cases, you can override input parameters with an Assignment step.
If you define a field to override the same parameter in both the Assignment step and the Data Task step, the taskflow considers the value assigned in the Data Task step.
If you use a Data Task step to assign values to input or in-out parameters, the assignments must be independent of each other. If you use an Assignment step to assign values to input or in-out parameters, an assignment operation can use the result of a previous assignment operation in the same step.
For example, you have two source objects, SO1 and SO2. You want to override SO1 with the value
Account
and override SO2 with the value
SO1
. Use the Assignment step to override the parameters.
The following image shows the source object
SO2
overridden with the value of
SO1
:
When you configure the Data Task step to override the parameter file connection and parameter file object, you must ensure that both the parameters, that is, source object and source connection are passed either through the parameter file or taskflow. Otherwise, an error occurs.
