R&D on Classic rule project vs Decision service project
1. Define Rule set parameters in Classic rule project and decision service
projects:
1.1 Classic rule projects:
In Classic rule projects after creating the bom we can directly define the Rule set
parameters by clicking the “Define parameters” in rule project map or Right click
on the rule project go to properties and click on rule set parameters. In Classic
rule projects without defining the variable set we can define rule set parameters
directly.
1.2
Decision Services project:
In Decision services project before going to define the rule set parameters first
define the variable set. In order to add the variable set first add decision
operation( click on “add decision operation” in the decision service map).After
adding decision operation then add variable set by selecting the decision
operation. After adding variable set then click on the decision operation name and
go to signature tab add rule set parameters by selecting from the variable set. In
Decision service projects we can’t define the rule set parameters without creating
the variable set.
2. Process of deploying Rule app in to RES using Classic rule projects and
Decision service projects:
2.1 Classic rule projects:
In Classic rule projects we can create the rule app project and directly deploy in to
the Rule execution server (double click on the Archive file and click deploy (or)
right click on the rule app project and click on rule app and click on deploy)
2.2
Decision Services project:
In Decision services project you need to follow the below steps
 First create the deployment configuration by clicking “create deployment
configuration” in the Decision service map. After the completion of deployment
configuration we got one error message displayed on the deployment overview
tab.

decision operation by selecting existing decision operation.
Double click on the rule project and click on “deploy rule app” in decision
service map.
After deploy rule app then double click on “deployment configuration name” add
the target server and click on “proceed to rule app deployment”
Creating target server:


Double click on the created deployment configuration name
Click on the target servers tab
Add new target server
3. Using of Rule flow in Decision service project:
In Decision Services project if you are executing the rules based on rule flow then you
must select “use main rule flow” in rule flow section (Double click on decision operation
name  click on Overview tab  go to Rule flow section  select “use main ruleflow”
and choose a ruleflow)
