Spectrum patch requirement
Please refer to the CAPM compatibility matrix here: Compatibility Matrix. Depending on the version of CAPM and Spectrum you will need to apply a ptf patch in your Spectrum environment for the life cycle state updates to work
To get a ptf patch for Spectrum you will need to open a case with the Spectrum team
Note: Spectrum 10.2 should support the life cycle state change feature out of the box
