Hi Vinz,
First, did you copy standard application configuration HRESS_AC_PERSINFO to e.g. ZHRESS_AC_PERSINFO? After that you go to configure your launchpad to use this copied configuration (tCode LPD_CUST).
Second, copy AppController configuration HRESS_CC_PER_CONFIG to ZHRESS_CC_PER_CONFIG, then set action to hide UIBB of Family Members for China
Lastly, go to ZHRESS_AC_PERSINFO configuration, at top left of the screen, click Change --> Global Settings --> set configuration name to ZHRESS_CC_PER_CONFIG.
Also, please ensure that your user id used for testing is tied to a personnel number with country group China.
Please let me know if this solves your problem. Hope it helps! Cheers!
