In the latest project, an OLAP table was employed, featuring distinct attributes for each individual case.
Certain attributes are not universally applicable across all cases. We know that Celonis automatically inserts "-" in null values; however, we aim to modify this default value to "no information." Despite attempts using functions such as coalescence, case when is null, case when isnull(), none of these methods have proven successful.
Could you kindly suggest an alternative approach? If additional details are required, please feel free to request them.
Thank you for your assistance.
