Hi Experts,

Would like to know the app param Export Task Categories functionality. If we have any tasks with not null task category and if we set the app param Export Task Categories value as Null, should we map the app param value to not null values and do not leave the value as Null incase we do not want those tasks to go to PSO ? 
Do we have any other option or another param which can be set to restrict these tasks from interfacing to PSO?
