Unfortunately these are not the same names In Automation, it is called CT_DifferentialPairPhaseToleranceMax and in CES is called DP_PHASE_TOL_MAX.
OK you are using the new CES automation. I checked with engineering unfortunately this value is not supported.
You will want to open an Bright Idea on it and if this is mission critical, the original CES automation does support it.
It is a free license but, you need to get approval to use it. The approval form used to be on this website but, I can't find it. You may need to contact support to get it.
