The "Conversion Value Supported" is the conversion value to which a campaign contact contributed without getting assigned the conversion (according to the standard attribution).

Calculation    Contact Value in Customer Journey - Conversionvalue                                                                       

Example for the standard attribution "Last Campaign":

If a source appears twice in a Customer Journey without getting the conversion assigned, we count the value twice. So if the customer journey was:

Display > Display > SEM: 100€
Display > Affiliate: 20€

The Conversion Value Supported would be 220€
