The SYS1.CSSLIB is possibly defined to the PROGRAM profile * or ** , and UACC was defined to something other than READ.
Release : 15.0
IBM recommends (in "Maintaining a clean environment in BASIC or ENHANCED mode") that this profile have UACC(READ) to this data set.
The solution would be to add this UACC(READ) access:
RALTER PROGRAM * ADDMEM('SYS1.CSSLIB'//NOPADCHK) UACC(READ)
RALTER PROGRAM ** ADDMEM('SYS1.CSSLIB'//NOPADCHK) UACC(READ)
Depending on the PROGRAM file the SYS1.CSSLIB is defined.
