Defining rules with a routing policy (deprecated)

When you establish a Routing Policy for a BPD activity, you establish rules to determine the recipients of the activity as a runtime task.

Before you begin

To perform this task, you must be in the IBM® Process Designer desktop editor.

Using rules, your task assignments can be dynamic, which ensures that activities are routed to the appropriate individuals.

When defining rules, you can choose from the following rule types:

Table 1. Available rule types
Rule type	Description
Swimlane	Routes activities to users based on whether they are the default lane participants.
Participant Rule	Selects users according to group membership.
User Attribute Rule	Selects users based on user attributes.
Expression Rule	Selects users who match a particular expression that you provide.

Open the Process Designer desktop editor.
Open a process application that contains a business process definition (BPD).
Click an activity in the BPD.
In the Properties page, click Assignments.
In the Assign To list, select Routing Policy (Deprecated). The Routing Conditions (If) section becomes available.
Under Routing Conditions (If), click Add a column, and select the variable for which you want to add the condition.
In the table, select Adv. The Advanced Assigned To (Then) section is populated.
Under Advanced Assigned To (Then), click all in the following statement:
Advanced Lane Participants are users who match all of the following rules:

Choose all or any.

If you choose all, the runtime task is assigned to users who match all specified rules. If you choose any, the runtime task is assigned to users who match at least one of the specified rules.

If none of the conditions that you specify are met, IBM Business Process Manager assigns the task to the swimlane for the rule to which this Advanced Assignment applies.
Click Add Decision to choose the type of rule to add.
For example, you can define the following Advanced Lane Participant group (team) rules in the group properties:

Advanced Lane Participants are users who match all of the following rules:
- Who belong to the Finance Managers group
- Who have an attribute Level 1 Loans greater than tw.local.loanAmount
- Who match expression tw.local.Recipient
The Add Decision... option adds other rules to the list.

Supply the necessary information for the specified type of rule.
