I have 2 customer fields added to UI using EEW and have custom table for maintaining field values. need to add F4 help for field1 ( field1 and field2 values needs to be displayed in F4 help list) and field2 should get value when we hit the particular entry from field1 F4 help list.

Hi,
   You can implement the Get_V* method for the field1 attribute and use the following code to populate both field1 and field2 as output paramters for your F4 help.
  DATA:
    ls_map    TYPE if_bsp_wd_valuehelp_f4descr=>gtype_param_mapping,
    lt_inmap  TYPE if_bsp_wd_valuehelp_f4descr=>gtype_param_mapping_tab,
    lt_outmap TYPE if_bsp_wd_valuehelp_f4descr=>gtype_param_mapping_tab.
  ls_map-context_attr = '<STRUCT.field1>'.
  ls_map-f4_attr      = 'field1'.
  APPEND ls_map TO lt_outmap.
  ls_map-context_attr = '<STRUCT.field2>'.
  ls_map-f4_attr      = 'field2'.
  APPEND ls_map TO lt_outmap.
<fill the lt_inmap (input parameters) as per your requirement>
    CREATE OBJECT rv_valuehelp_descriptor TYPE cl_bsp_wd_valuehelp_f4descr
      EXPORTING
        iv_help_id        = '<your search help id>'
        iv_help_id_kind   = if_bsp_wd_valuehelp_f4descr=>help_id_kind_name
        iv_input_mapping  = lt_inmap
        iv_output_mapping = lt_outmap.
Note: In your DDIC search help, define field1 and field2 as output parameters in SE11.
Reward if it works!
