Configure process data
You must configure the source data so that ARIS Process Mining can use the data to perform process analyses. That means, you must specify the columns of the uploaded source table that contain the case IDs, activities and timestamps. In any case, this information is needed to recreate the processes from the source data. The data set must contain exactly one activity table.
Click Data modeling in the Data set panel. The Data modeling section opens.

Click + Add tables. The Select tables dialog opens.
Select the table in Available tables box. The table is added to the Selected tables box.

Click Select. The table is added to the Data modeling page.

Click ... More options on the table icon > Change table role. The Select data table type dialog opens in the Edit data table wizard. On this page you can specify the type of data that the source table contains.
Ensure that the table contains the activity data, select Activity table and click Next.
An Activity table contains event log data. The table must include the case ID, activity, and timestamp. An Enhancement table contains data that can be used to extend the event log data.

Click Next. The Configure activity columns page opens.
Specify the activities table type in the corresponding drop-down menu. Case ID is selected by default. Linked activities is required for data extracted from an SAP source system.
Specify the following columns. To select a column, click the column content. ARIS Process Mining uses the columns to recreate your processes.
Specify the column that contains the case IDs (required).
Specify the column that contains the activities (required).
Specify the column that contains the start time of the activities (required).
Specify the column that contains the activity IDs (optional).
Specify the column that contains the end time of the activities (optional).

Click OK.
You have configured the source table as activity table for the current data set.
ARIS Process Mining now has enough information to load the data into the process storage for further analyses.
