About Case Nodes in Cognitive Analytics

A Case node is a node that you can use in a cognition to set up scenarios in which the output values of the node are changed automatically based on specific input values. Throughout this documentation, we refer to each defined scenario as a Case.

Each Case within the Case node has one Case value and one output value. If the input value for the Case node matches a Case value, the GE Digital APM system will use the corresponding output value defined for that Case.

There are two types of Cases in the Case node, which we refer to as the If Case and the Default Case throughout this documentation:

If Case: The type of Case that is executed if the input value matches a Case value that you specify. You can define one or more If Cases for a given Case node.
Default Case: The Case that is executed by default if the input value does not match any of the Case values that you specified. There is only one Default Case for a given Case node.

Node Properties

The Properties window for a Case node contains the items that are described in the following table.

Item	Description	Notes
If box	Specifies the field that provides the input value(s) you want to compare to each Case value in the Equals box in order to determine the output(s) of the Case node.	None
Equals box	Specifies the Case value of the If Case to be executed when matching the input value from the field that was chosen in the If box.	You can use the and buttons in the Equals box row to add or delete If Cases in the Case node. When you add or delete an If Case, the corresponding Use box is added or deleted.
Use box	Specifies the output for the corresponding Case value found in the Equals box.	None
Default box	Specifies the output of the Default Case. The Default Case will be executed if the input value from the field that was chosen in the If box does not match any Case values defined in the Equals boxes.	You cannot delete the Default Case from the Case node.

Example

Consider the following nodes and connections in which values from a numeric-based Order Priority input field are converted to text by the Order Priority Case node. The values are then written to the Event Priority output field.

Case Node Example

As shown in the following image, you can use the Properties window of the Order Priority Case node to indicate that the output value of the Case node will differ depending on the values associated with the Order Priority input field.

Case Node Properties

In this example, the following output values would be produced by the Case node:

Input Value from Order Priority Input Field	Output Value from Order Priority Case Node
1	Low
3	High
7	Unknown
1	Low
2	Medium
