Hi Sivakishore,
Try adding the below code in do_init_context method
DATA: lr_col TYPE REF TO if_bol_bo_col.
DATA: lr_ent TYPE REF TO cl_bsp_wd_value_node.
CREATE DATA ls_data TYPE "give your view structure here.
CREATE OBJECT lr_ent
EXPORTING
iv_data_ref = ls_data.
lr_col ?= me->typed_context->context node name->collection_wrapper.
lr_col->add( lr_ent ).
Then try adding below code in do_prepare_output
if me->view_group_context->IS_VIEW_IN_DISPLAY_MODE( ) EQ abap_false.
me->view_group_context->SET_ALL_EDITABLE( ).
endif.
do the same step as mentioned by deepika for set_view_group_Context method.
if still did not work with above process, you can modify get_i method of the attributes with code
rv_disabled = 'FALSE'.
this will enable the attribute.

Dharmakasi.
