Hi Ravi,
Use the Component WDR_SELECT_OPTIONS to include select options in Web Dynpro ABAP. Follow these steps:
1. In your Component , "Used Componet" tab add Component WDR_SELECT_OPTIONS . Component Use can be any name that you want to give, eg SELECT_OPTIONS
2. Go to the View where you want to include the Date Select Options. I am assuming that you already have an Attribute of Type DATS in your context.
3. View: Properties Tab:Create Controller Usage and select
SELECT_OPTIONS     WDR_SELECT_OPTIONS                   
SELECT_OPTIONS     WDR_SELECT_OPTIONS     INTERFACECONTROLLER
4. View Layout Tab:Include a View Container. In this view container we will show the Date Select Options.
5. View Attributes Tab: Create Following two attributes:
M_HANDLER type IF_WD_SELECT_OPTIONS
M_WD_SELECT_OPTIONS type IWCI_WDR_SELECT_OPTIONS
6: View Methods Tab: Create a method eg CREATE_SELECTION_SCREEN. Call this method in the WDDOINIT of the view.
7:CREATE_SELECTION_SCREEN: Write following Code:
* Data Declaration
  data:
        lt_range_table TYPE REF TO DATA.
  data:
        lr_componentcontroller TYPE REF TO IG_COMPONENTCONTROLLER,
        lr_componentusage TYPE REF TO IF_WD_COMPONENT_USAGE.
* Execution
*  Create Used Component
  lr_componentusage = wd_this->wd_cpuse_select_options( ).
  if LR_COMPONENTUSAGE->HAS_ACTIVE_COMPONENT( ) is initial.
    lr_componentusage->create_component( ).
  endif.
*  Get pointer to interface controller of select options
  wd_this->M_WD_SELECT_OPTIONS = wd_this->wd_cpifc_select_options( ).
* initialize selction screen
  wd_this->M_HANDLER = wd_this->M_WD_SELECT_OPTIONS->init_selection_screen( ).
*  Create Range Table for: Date
  CALL METHOD WD_THIS->M_HANDLER->CREATE_RANGE_TABLE
    EXPORTING
      I_TYPENAME     = 'DATS'
    RECEIVING
      RT_RANGE_TABLE = lt_range_table.
* Add Selection Field for: Date
  CALL METHOD WD_THIS->M_HANDLER->ADD_SELECTION_FIELD
    EXPORTING
      I_ID                         = '<name of date attribute in the context>'
*      I_WITHIN_BLOCK               = MC_ID_MAIN_BLOCK
*      I_DESCRIPTION                =
*      I_IS_AUTO_DESCRIPTION        = ABAP_TRUE
      IT_RESULT                    = lt_range_table
*      I_OBLIGATORY                 = ABAP_FALSE
*      I_COMPLEX_RESTRICTIONS       =
*      I_USE_COMPLEX_RESTRICTION    = ABAP_FALSE
*      I_NO_COMPLEX_RESTRICTIONS    = ABAP_FALSE
*      I_VALUE_HELP_TYPE            = IF_WD_VALUE_HELP_HANDLER=>CO_PREFIX_NONE
*      I_VALUE_HELP_ID              =
*      I_VALUE_HELP_MODE            =
*      I_VALUE_HELP_STRUCTURE       =
*      I_VALUE_HELP_STRUCTURE_FIELD =
*      I_HELP_REQUEST_HANDLER       =
*      I_LOWER_CASE                 =
*      I_MEMORY_ID                  =
*      I_NO_EXTENSION               = ABAP_FALSE
*      I_NO_INTERVALS               = ABAP_FALSE
*      I_AS_CHECKBOX                = ABAP_FALSE
*      I_AS_DROPDOWN                = ABAP_FALSE
*      IT_VALUE_SET                 =
*      I_READ_ONLY                  = ABAP_FALSE
*      I_DONT_CARE_VALUE            =
*      I_EXPLANATION                =
      I_TOOLTIP                    = 'Select Date'.
8: To Fetch Data entered in the selection field, write following code on action of button click:
  data:
        lt_date type REF TO DATA.
FIELD-SYMBOLS:
                 <fs_date> TYPE table.
  *  retrieve Date from Select Options
  CALL METHOD WD_THIS->M_HANDLER->GET_RANGE_TABLE_OF_SEL_FIELD
    EXPORTING
      I_ID           = '<attrib_name>'
    RECEIVING
      RT_RANGE_TABLE = lt_date.
*  assign Date Field Symbol
  ASSIGN lt_date->* to <fs_date>.
9: Windows Window Tab: In the View Conatiner, embed the WND_SELECTION_SCREEN view from SELECT_OPTIONS component Usage of  WDR_SELECT_OPTIONS component.
