When doing a package ship job the symbolics that are defined in the job C1BMXJOB are not being resolved at all. They are staying to the value that is defined and not using the correct SCMM@SYM defined values. The file is in the allocated library in the steplib and all indications are is that should allow the correct options to be used.
Skeleton C1BMXHJC in prefix.qual.NDVR.CSIQSENU was customized by adding a couple of /*ROUTE statements at the end.
The problem was that the skeleton was missing the last statement ')IM SCMM@SYM' which caused the problem.
Skeleton SCMM@SYM sets values for symbolics like I@PRFX which are used later during the JCL generation. Since the symbols are not set correctly, they resolve to null and result in incorrect dataset names.
