In the big view, system symbols are over 20 years old. For many years, symbols were honored for STC and TSU but not for batch. IBM was reluctant to support batch for reasons mentioned by Lizette and others. I participated in more than one open discussion at SHARE where different folks had very convincing reasons for symbols to be substituted in various incompatible ways. But symbols had to be managed in only one way, and there was forceful disagreement.
So IBM left it up to the customer whether to honor symbols in batch. If it works for you, turn it on. Otherwise don't. But you should move gradually. Be prepared to back out. Since system symbols in batch are a (relatively) new thing, you need to verify that in your environment you get the results you expect. Caveat emptor. . .

So this may or may not apply You have 3 LPARs in a plex. They all share a JES2 MAS Job A is submitted on LPAR1 but is converted on LPAR2. The symbols the job needs is only on LPAR1 - so the conversion on LPAR2 will either get wrong symbols or no symbols. If your single LPAR, you probably do not need to worry as much. If you more LPARs in a PLEX and the potential for symbols to be different on them, and jobs can convert anywhere, you might have some challenges.
