How to Upload/Open pdf or excel ?

Question

1. How to upload a Excel or PDF file into SAP through ABAP WedDynpro?
    Upload file name convention is <salesordernumber>_<itemnumber>_YYYYMMDD.xls or
    <salesordernumber>_<itemnumber>_YYYYMMDD.pdf
2. There is a sales order report which contains header and item details. With addition to these details there is 'Reamrks'    
    column. Previous uploaded filename (it can appear either as icon with file name or just file name with file type)  needs to   
    display in reamrks column.
    Can anybody help me how to do part 2? I know only how to do part 1.
Regards,
Meera.

Hi Sahai,
I fallowed your instructions and able to call Component2 in a seperatre browser
but unable to see the value. Please see below sample piece of design and code
and correct me.  Variable lv_contract_number contains null value.
Creating Application 2
Go to SE80,
Step1.
Create Webdynpro Componet:
Name:           ZAPPLICATION2
Description:     Application 2(Data Receiver)
Type:          Web Dynpro Component
Window Name:      ZAPPLICATION2
View Name:     MAIN2     
Save and Activate Component
Step2.
Create WebDynpro Application:
Place the mouse cursor on component name(ZAPPLICATION2) and
right click and choose CREATE->Webdynpro Application
In the pop-up box enter enter applicaiton name and description
Application: ZBROWSER_TAB2
Name:        Example program 2
Save and Activate Component
Step3.
Create a node in COMPONENT CONTROLLER
Click on 'COMPONENT CONTROLLER' and go to context tab & create a node with field 'CONTRACT_NUMBER'.
Attribute property is 'EBELN'
Node Name:      ZCONTRACT_DETAIILS
Attribute Name: CONTRACT_NUMBER
Go to property tab of node and check the field "Interface Node"
SAVE the application.
Step4.
View design
Go the View "MAIN2" and Place a UI Element 'INPUT'.
Bind the attribute "CONTRACT_NUMBER" to 'value' parameter in the properties tab.
Go to "Methods" tab in the same view and write below code in the "WDDOINIT" method
  DATA lo_nd_contract_detaiils TYPE REF TO if_wd_context_node.
  DATA lo_el_contract_detaiils TYPE REF TO if_wd_context_element.
  DATA ls_contract_detaiils TYPE wd_this->element_contract_detaiils.
  DATA lv_contract_number TYPE wd_this->element_contract_detaiils-contract_number.
  lo_nd_contract_detaiils = wd_context->get_child_node( name = wd_this->wdctx_contract_detaiils ).
  lo_el_contract_detaiils = lo_nd_contract_detaiils->get_element( ).
get single attribute
  lo_el_contract_detaiils->get_attribute(
    EXPORTING
      name =  `CONTRACT_NUMBER`
    IMPORTING
      value = lv_contract_number ). 
"=========================================
Creating Application 1
Go to SE80,
Step1.
Create Webdynpro Componet:
Name:           ZAPPLICATION1
Description:     Application 1(Data Sender)
Type:          Web Dynpro Component
Window Name:      ZAPPLICATION1
View Name:     MAIN1     
Save and Activate Component
Step2.
Create WebDynpro Application:
Place the mouse cursor on component name(ZAPPLICATION1) and
right click and choose CREATE->Webdynpro Application
In the pop-up box enter enter applicaiton name and description
Application: ZBROWSER_TAB1
Name:        Example program 1
Save and Activate Component
Step3.
Create a interface node in COMPONENT CONTROLLER
Click on 'COMPONENT CONTROLLER' and go to context tab & create a node with field 'CONTRACT_NUMBER'.
Attribute property is 'EBELN'
Node Name:      ZCONTRACT_DETAIILS
Attribute Name: CONTRACT_NUMBER
Go to property tab of node and check the field "Interface Node"
SAVE the application.
Step4.
View design
Go the View "MAIN1" and Place Two UI Elements 'INPUT', 'LABEL' & 'BUTTON'.
Go to properties tab of UI Element "INPUT' and Bind the attribute "CONTRACT_NUMBER"
to 'value' parameter in the properties tab.
Button name is "Call Application 2"
On Action (Event) for the button (call application 2) is 'APP2'.
Go to "Actions" tab and click on event "APP2" and write below code to call application 2.
DATA LO_WINDOW_MANAGER TYPE REF TO IF_WD_WINDOW_MANAGER.
DATA LO_API_COMPONENT  TYPE REF TO IF_WD_COMPONENT.
DATA LO_WINDOW         TYPE REF TO IF_WD_WINDOW.LO_API_COMPONENT  = WD_COMP_CONTROLLER->WD_GET_API( ).
LO_WINDOW_MANAGER = LO_API_COMPONENT->GET_WINDOW_MANAGER( ).
CALL METHOD LO_WINDOW_MANAGER->CREATE_EXTERNAL_WINDOW
  EXPORTING
    URL            = 'HTTPS://XXXXXXXXXXXXXXXXXXX/xyz'
    MODAL          = ABAP_FALSE
    HAS_MENUBAR    = ABAP_TRUE
    IS_RESIZABLE   = ABAP_TRUE
    HAS_SCROLLBARS = ABAP_TRUE
    HAS_STATUSBAR  = ABAP_TRUE
    HAS_TOOLBAR    = ABAP_TRUE
    HAS_LOCATION   = ABAP_TRUE
  RECEIVING
    WINDOW         = LO_WINDOW.LO_WINDOW->OPEN( ).
    IF SY-SUBRC EQ 0.
      ENDIF.
save, activate and run the application.
Now you can see input field and a button with text "Call Application 2".
Enter '100002' in inputfield and click on button.
Then you will see second application in a separate browser.
