HI Guys,
I found my solution by myself. Below is the solution , hope this will help others:-
Retrieve data from MDM  using MDM ABAP API.
Step- 1. Create structure in SAP with the same name as that of MDM field code for MDM Main table.
Step-2. Create another structure in SAP having all  lookup fields of MDM , fieldname in ECC must be same as that of MDM field
code.
Step-3.Create structure in SAP for  individual lookup field(Single Field only)   with the same name as MDM Field code.
Step-4.
DATA: IT_QUERY            TYPE STANDARD TABLE OF MDM_QUERY,  "MDM_QUERY_TABLE,
      WA_QUERY            TYPE  MDM_QUERY,
      WA_CDT_TEXT         TYPE  MDM_CDT_TEXT,
      IT_RESULT_SET_KEY   TYPE  MDM_SEARCH_RESULT_TABLE,
      WA_RESULT_SET_KEY   TYPE  MDM_SEARCH_RESULT,
      WA_STRING           TYPE  STRING.
DATA:<Internal table> TYPE STANDARD TABLE OF <SAP Str Having all LOOKup Fields>    
DATA: :<Internal table>TYPE STANDARD TABLE OF <SAP Str one LOOKup field>,
     <Workarea> LIKE LINE OF :<Internal table>.
*PASS LOGICAL OBJECT NAME.
V_LOG_OBJECT_NAME = 'Logical object name defined in Customization'.
Define logon language, country & region for server
WA_LANGUAGE-LANGUAGE = 'eng'.
WA_LANGUAGE-COUNTRY = 'US'.
WA_LANGUAGE-REGION = 'USA'.
TRY.
    CREATE OBJECT LR_API
      EXPORTING
        IV_LOG_OBJECT_NAME = V_LOG_OBJECT_NAME.
ENDTRY.
CONNECT to repository. Apply particular logon language info
CALL METHOD LR_API->MO_ACCESSOR->CONNECT
  EXPORTING
    IS_REPOSITORY_LANGUAGE = WA_LANGUAGE.
*NOW PASS ITEM NO AND GET KEY FROM MDM.
CLEAR WA_QUERY.
WA_QUERY-PARAMETER_CODE  = <MDM FIELD CODE>. "Field code
WA_QUERY-OPERATOR        = 'EQ'. "Contains
WA_QUERY-DIMENSION_TYPE  = 1. "Field search
WA_QUERY-CONSTRAINT_TYPE = 8. "Text search
WA_STRING                = <Field Value>.
GET REFERENCE OF WA_STRING INTO WA_QUERY-VALUE_LOW.
APPEND WA_QUERY TO IT_QUERY.
CLEAR WA_QUERY.
*PASS ITEM NUMBER AND GET RELATED KEY FROM MDM.
TRY.
    CALL METHOD LR_API->MO_CORE_SERVICE->QUERY
      EXPORTING
        IV_OBJECT_TYPE_CODE = <MDM Main Table>
        IT_QUERY            = IT_QUERY
      IMPORTING
        ET_RESULT_SET       = IT_RESULT_SET_KEY.
  CATCH CX_MDM_COMMUNICATION_FAILURE .
  CATCH CX_MDM_KERNEL .
  CATCH CX_MDM_NOT_SUPPORTED .
  CATCH CX_MDM_USAGE_ERROR .
  CATCH CX_MDM_PROVIDER .
  CATCH CX_MDM_SERVER_RC_CODE .
ENDTRY.
Pass record id into keys.
LOOP AT IT_RESULT_SET_KEY INTO WA_RESULT_SET_KEY.
  WA_KEYS = WA_RESULT_SET_KEY-RECORD_IDS.
ENDLOOP.
WA_RESULT_SET_DEFINITION-FIELD_NAME = <Look field name>.
APPEND WA_RESULT_SET_DEFINITION TO IT_RESULT_SET_DEFINITION.
CALL METHOD LR_API->MO_CORE_SERVICE->RETRIEVE
  EXPORTING
    IV_OBJECT_TYPE_CODE      = <MDM Main Table>
    IT_RESULT_SET_DEFINITION = IT_RESULT_SET_DEFINITION
    IT_KEYS                  = WA_KEYS
  IMPORTING
    ET_RESULT_SET            = IT_RESULT_SET.
LOOP AT IT_RESULT_SET INTO
        WA_RESULT_SET.
*PASS KEYS INTO MAIN TABLE TO GET Structure for FALT or Look up Table
  TRY.
      CALL METHOD LR_API->MO_CORE_SERVICE->RETRIEVE_SIMPLE
        EXPORTING
          IV_OBJECT_TYPE_CODE = <MDM Main Table>
          IT_KEYS             = WA_KEYS
        IMPORTING
          ET_DDIC_STRUCTURE =<SAP Strct having all Look up fileds of MDM>         
  ENDTRY.
  LOOP AT <SAP Strct having all Look up fileds of MDM> INTO <Work area>.
    CLEAR WA_KEYS.
    APPEND <Work area>-field name TO WA_KEYS.
    CALL METHOD LR_API->MO_CORE_SERVICE->RETRIEVE_SIMPLE
      EXPORTING
        IV_OBJECT_TYPE_CODE = <MDM Lookup table name>
        IT_KEYS             = WA_KEYS
      IMPORTING
        ET_DDIC_STRUCTURE   = <Single Structure in SAP For Lookup field>.
    READ TABLE <Single Structure in SAP For Lookup field>. INTO <Work Area> INDEX 1.
Here you can get the value of realted lookup fields associated with main table data.
  ENDLOOP.
ENDLOOP.
LR_API->MO_ACCESSOR->DISCONNECT( ).
