In general the Refresh level (see snap below) shown in the SIR output or SPLEVEL output of your VSE system will only be changed/modified when your system is upgraded via a Fast Service Upgrade (FSU). During a FSU the SPLEVEL.PROC will be replaced. The SIR command extracts the z/VSE Refresh level from the SPLEVEL proc.
When ever a PSB Bucket (summary of Hiper PTF's) or a RSL ( summary of PTF's based on a specific Refresh level) or ´single PTF is applied to your system then the Refresh Level won't be modified.
