RM 7.0 Custom Fields for Shopping Cart header

Hi Experts, We are upgrading from SRM 5.0 to 7.0. We created 2 custom fields using configure field control in Meta data handling (SPRO) and enabled them for visibility. When we tried to see these two custom fields, they didnt appear in the web dynpro component. Web dynpro details are below.

Webdynpro: /SAPSRM/WDCC_FPM_DO_SOCO_GAF_3

Window : IV_L_FPC_GAF_CA

view : V_AO_SOCO_GAF_3

Field : zzXXXX
