Well, your keyword ID is not a JCL keyword - it is in your program control cards but you do not mention which program you are using. Probably something to do with DB2? In which case probably posting in DB2 would be a better idea in future.
JCL Symbol Substitution is not done for data cards. You'll need to pre-process your JCL and cards and then SUBmit the output., or kick into the INTRDR (if you are able) depending on how you do your own substitution.
