How to Configure the Decide Shape

Decide shape

Each branch of a Decide shape, except the else branch, has a rule associated with it. You can use BizTalk Expression Editor to create a Boolean expression in the rule that is evaluated for the execution of that branch. Because the else branch implies the negation of the Boolean expression in the previous branch, it does not have an expression associated with it.

Below the rule or else clause, a branch of a Decide shape can contain additional shapes, just like any other part of the orchestration.

To configure a Decide shape

1. If BizTalk Expression Editor is not visible, right-click the rule and click Edit Boolean Expression, or in the Properties window, click the Ellipsis (...) button for the Expression property.

2. In BizTalk Expression Editor, create a Boolean expression for each branch except the Else branch. For example,

   myMessage.Total > 1000  
   myObject.IsValid()  
   myMessage.VIP == true  
   

To add a branch to a Decide shape

1. Right-click the Decide shape, and then click New Rule Branch.

   —Or—

2. Drag a new shape between two existing branches.

   Note

   To remove a branch from a Decide shape, right-click the branch you want to remove, and then click Delete, or select the rule branch and press the DELETE key.
