Putting in maintenance for Common Services. Completed the SMP/e work.
Upon IPL, get a U0203 and the CAIENF stc drops.
Backed out the code with another IPL.
Release : 15.0
Component : ENF COMMON COMP
Libraries with maintenance applied not added to APF list
Had applied maintenance but new libraries not added to APF list.
Corrected that and problem resolved.
Refer to the r15.0 Common Services documentation which lists the LINKLIST/APF requirements for the CCS Target libraries
