IIRC you need to remove the dataset you intend to delete from the SMFPRMxx member, set that member as active T SMF=xx then you can delete and redefine, I've done this a couple of time, works well that way, I have 3 SMFPRMxx members still setup to do this. We're using log streams now but the SMF MAN datasets are still defined in the member for backup
