Custom data to be displayed as a column in the instance list must first be defined as persisted variables.

Example:

• customer: String
  
• productName: String
• complainDetails: String
• status: String
• formTimeout: Integer

In the Instance_List_Example, the entered data is transferred from the form Form_ComplaintInput via the mapping operations mapFromForm and persistDataForInstanceList to the persisted variables .

Persisted variables are available in the column configuration of the instance list.

To add a new column, click the Add button. A new empty line will be added at the bottom of the column configuration.
Click in the field Name. A drop-down menu opens with all persisted variables that have been created.
Select the variable whose values you want to have displayed in the respective column. Fill in the field Label, choose any other desired options, and click Save. 

In the executed application the values of the selected persisted variables are each displayed in a separate column of the instance list.
