Hi Vinit,
That depends on your SLD strategy. Usually there should be one master SLD (i.e. Production) which synchronites at least technical data via data suppier bridge to all other SLDs. To get objects like business systems, products, etc. in the Production SLD, only transports or file exports should be allowed. This ensures that the master SLD is untouched, except via transports.
Best would be to read the SLD master guide to get the proper setup for your landscape:
Best Regards
