If the SOURCEID operand was used during RECEIVE processing to group all those SYSMODs processed, you can choose to install only that set of SYSMODs. This can be done with the SOURCEID operand of the APPLY command. Suppose you received an ESO containing service levels PUT0701 and PUT0702. The ESO contained ++ASSIGN statements that assigned each PTF a SOURCEID value corresponding to the service level that it is part of. Now you want to install all the applicable PTFs from those tapes into the target libraries described by zone MVSTST1. You can do this with the following commands:

SET      BDY(MVSTST1)       /* Process MVSTST1 tgt zone.  */.
APPLY    SOURCEID(PUT0701,  /* Process these service      */
                  PUT0702)  /* levels                     */
         GROUP              /* and any requisites.        */.
