What is CA RS (CA Recommended Service) and where can documentation be found?
CA RS stands for CA Recommended Service. A CARS level is a list of ++ASSIGNS, PTF's FMIDs for all CA Mainframe products.
A CARS file comes out monthly and is not cumulative, for example CARS1901. CARS1901 is a file of ++ASSIGNS associating a SYSMOD with a sourceid of CARS1901. These would be all non-PE'd published PTF's for all CA Mainframe products published in January 2019. It is a convention that simplifies maintaining the CSI.

Which PTFs are eligible for CA Recommended Service (CA RS) for z/OS? (From FAQ's)
PTFs qualify for the new CA RS for z/OS level of service if any of the following are true:
a. PTF was published for 30 days, is not already in a CA RS, and passed IST lab testing and customer use.
b. HIPER was published for 30 days, is not already in a CA RS, and passed IST lab testing and customer use.
c. PRP was published for 30 days, is not already in a CA RS, and passed IST lab testing and customer use.
Note: PTFs that do not pass the 1ST lab testing criteria will remain in the CA RS for z/OS level but ERROR HOLDDATA will be created to flag the PTF as PE (PTF in Error) to prevent the APPLY until a PRP (PTF Resolving the PE PTF) comes available. 4.
