Configure an Exclusive Split

This section describes how to split the sequence flow in a microflow with the help of an exclusive split.


Open the microflow, or if necessary create a new one. If you do not know how to add documents to your project, please refer to this article.

If your exclusive split is intended to use an enumeration, make sure it is either created by the microflow or passed to it.

Add an ‘Exclusive split’ to the microflow and double click on it. If you do not know how to do this, please refer to this article.

In the menu that pops-up, you can choose the ‘Exclusive split type’ using the radio buttons.

If you choose ‘Expression’, you can enter a microflow expression the exclusive split should check for, with boolean or enumeration value as result.

If you choose ‘Rule’, you can press the ‘Select’ button to select the rule you want to use in the new menu that appears.

After this the parameter area will be filled with parameters that have to be passed to the rule. Select a parameter and press the ‘Edit parameter value’ button to bring up menu where you can enter the value for the parameter.

In the new pop-up window you can enter a microflow expression for the variable or value you want to pass to the rule.

Now that the exclusive split has been configured, you will notice that the sequence flow paths leading out of it have turned red. Right-click on such a path and then under ‘Condition value’ choose the boolean or enumeration value for which this path should be executed.

Create additional paths for every possible boolean or enumeration result from the expression or rule you entered for the exclusive split.

Add activities and, if necessary, end events to these paths to finish the microflow.

Exclusive splits and numerical ranges

Exclusive splits will split the sequence flow based on the result of their expression or rule, which is either a boolean or enumeration value. As a result, if you want to split the sequence flow according to numerical ranges of a variable, this is not possible to achieve with a single exclusive split.

However, it is still possible to do this by using several exclusive splits to check at the boundaries of the numerical ranges.

For example in the above microflow customer ranks are based on the number orders placed, with the ranges being 0-5, 5-10, 10-15 and greater than 15. To split the sequence flow into these ranges, multiple exclusive splits are used which test whether or not the number of orders placed exceeds a boundary of a range, with boolean as result. The first exclusive split for example checks if the number of orders placed is greater than 5; if this is not the case the customer is assigned ‘Basic’ rank, whereas if this is the case the sequence flow leads to a new exclusive split checking if the customer ordered more than 10 times. If this is not the case, the customer falls in the 5-10 range and is assigned ‘Bronze’ rank.
