Hi Lily,
To read the URL parameters, you need to right the following code in the HANDLEDEFAULT method
of the your default window controller.
DATA : it_parameter TYPE tihttpnvp,
         wa_parameter TYPE ihttpnvp.
DATA lo_nd_url_param TYPE REF TO if_wd_context_node.
DATA ls_url_param TYPE wd_this->element_url_param.
" Get all URL parameters
CALL METHOD wdevent->get_data
    EXPORTING
      name = if_wd_application=>all_url_parameters
    IMPORTING
      value = it_parameter.
" Get parameter values
CLEAR wa_parameter.
READ TABLE it_parameter WITH KEY name = 'PERNR' INTO wa_parameter.
IF sy-subrc EQ 0.
    ls_url_param-pernr = wa_parameter-value.
ENDIF.
CLEAR wa_parameter.
READ TABLE it_parameter WITH KEY name = 'SUBTY' INTO wa_parameter.
IF sy-subrc EQ 0.
    ls_url_param-subty = wa_parameter-value.
ENDIF.
CLEAR wa_parameter.
READ TABLE it_parameter WITH KEY name = 'BEGDA' INTO wa_parameter.
IF sy-subrc EQ 0.
    ls_url_param-begda = wa_parameter-value.
ENDIF.
CLEAR wa_parameter.
READ TABLE it_parameter WITH KEY name = 'ZZPRNTOPT' INTO wa_parameter.
IF sy-subrc EQ 0.
    ls_url_param-zzprntopt = wa_parameter-value.
ENDIF.
" Save URL parameter to context
lo_nd_url_param = wd_context->get_child_node( name = wd_this->wdctx_url_param ).
lo_nd_url_param->set_static_attributes(
     static_attributes = ls_url_param ).

Hi Santosh,
You can read parameters send from one WebDynpro Component to another component by adding code in "HANDLEDEFAULT" Event Handler method ( Window )of your target Web Dynpro Component.
data: lt_parameter             type tihttpnvp,
         ls_parameter             type ihttpnvp.
lo_api_controller ?= wd_this->wd_get_api( ).
   call method lo_api_controller->get_message_manager
     receiving
       message_manager = lo_message_manager.
   clear : ls_parameter.
   refresh : lt_parameter[].
* Read all URL parameters
   wdevent->get_data( exporting name = if_wd_application=>all_url_parameters importing value = lt_parameter ).
if not lt_parameter[] is initial.
     clear : ls_parameter.
     read table lt_parameter into ls_parameter index 1.
     if ls_parameter-name = 'ACTION' and
        ls_parameter-value is initial.
       lv_flag = 'X'.
       clear : lo_msg.
       lo_msg = 'Action Parameter Missing in URL Link !'.
*         report message
       call method lo_message_manager->report_error_message
         exporting
           message_text = lo_msg.
     else.
     endif.

How to read url parameters from a decoded string

Hi,
Normally if I pass on a url string
test.cfm?name=abc&num=8, I can do url.name and url.num
to get the url parameters. But what if the url string is decoded by
javascript escape() function? The above url string becomes
test.cfm%3Fname%3Dabc%26num%3D8
How can I read url.name and url.num from this string?
Thanks!
Min

Escape is not really meant for urls because it encodes the
delimiters: ? &

How to read AL11 parameters in ABAP program

Hello SAP Masters,
I came across a requirement to read AL11 file parameters such as lastchanged day and lastchanged time of a particular file in directory. Can you guide me by providing either the function module name or any table where this information is stored, so that I can utilize something in ABAP program and get this information.
Your help is greatly appreciated!
Regards.

Keshav provided the correct response, but since you asked me - this is what AL11 does:
    PERFORM p6_to_date_time_tz(rstr0400) USING file-mtime
                                               file-mod_time
                                               file-mod_date.
BTW, that time/second value is the number of seconds since 1970.

Adding and reading the parameters from the WebDynpro Application URL

Hi,
I have a WebDynpro Application with two views. Based on the values populated by the user in the first view, I am pulling the data from database and populating the data in the second view. I do have a scenario where I have to skip the first screen and show the second screen directly. But, for the values that has to be populated in first screen, I am planning to append the parameters in the url and provide the link to the users via email.
Is it possible to add parameters to URL and read those Parameter values when user clicks on the URL.
Thanks & Regards

How to read the excel file using webdynpro abap?

Hi,
how to read and modify excel file using webdynpro abap?
Regards,
Pavani

For reading excel file follow the steps :
1. Use a File upload UI element and bind it with xstring.
2. Now your excel will be uploaded and stored in Xstring.
3. Convert Xstring to String data using FM 'HR_KR_XSTRING_TO_STRING'.
4. Now split the string at new line so as to make an internal table .
Ex . SPLIT l_string AT cl_abap_char_utilities=>newline INTO TABLE it_table.
here it_table is type table of string.
5.now loop at the internal table and separate the content of this table separated by tab.
Ex. SPLIT wa_table AT cl_abap_char_utilities=>horizontal_tab INTO TABLE it_new.
it_new type string_table.
6. For more info , refer this thread :

HTTP Sender - how to read URL Parameter USER id into Mapping

Hi,
My scenario is HTTP - XI - ABAP Proxy.
I wanted to capture USER id of the person who posted(HTTP) into XI(Mapping). How to read/evaluate the value of sap-user from querystring of URL ?
http://HOST:8008/sap/xi/adapter_plain?namespace=http%3A//abc.com/sales_oa&interface=MI_sales_OA&service=DEV_D&party=&agency=&scheme=&QOS=EO&<b>sap-user=SM9999</b>&sap-password=xxxxx&sap-client=001&sap-language=EN
please help.

Mallik,
Try URL Parameters in HTTP sender communication channel.
In the sender communication channel set Adapter Specific Message Attributes. Click on Apply URL Parameters. In Parameter1 put sap-user (U can query any URL parameter by giving its name as in the HTTP URL).
Now in SXMB_MONI, in inbound payload SOAP Header, under Dynamic configuration u can see the value of the user. Query the same in Mapping using Dynamic Configuration using keyName as UrlParamOne.

Reading Task Container in ABAP Webdynpro

Hi All,
I have to read the task container in ABAP Webdynpro to show the details on a ABAP interactive form which is embedded in WDA. For this I have approached in the following way.
1) Task is configured in SWFVISU with DYNPARM = WI_ID=${item.externalId}
2) Workitem is obtained in UWL and ABAPWebDynpro is launched when Task is executed from UWL
3) START is the "startup" plug that triggers the HANDLESTART method
     This method has WDEVENT as a standar parameter. Then the following code is for reading the URL parameters.
     wdevent->get_data(
    EXPORTING
      name = if_wd_application=>all_url_parameters
    IMPORTING
      value = l_url_parameters ).
READ TABLE l_url_parameters WITH KEY name = 'WI_ID' INTO l_url_parameter.
4) Set the WI_ID to a componentcontroller attribute
5) This attirbute is now binded to the WDDOMODIFYVIEW method of the View
6) Finally set the form elements attributes of the VIEW by reading the container based on the WI_ID
Problems:
1) I am not getting the form populated
2) The form is getting populated if I hardcode the WI_ID and execute the application directly from backend.
Please tell me where I might have gone wrong.
Thanks

Hi,
You can use the following code to get parameters from an URL
IWDProtocolAdapter protocolAdapter = WDProtocolAdapter.getProtocolAdapter();
IWDRequest request = protocolAdapter.getRequestObject();
String paramValue1 = request.getParameter("<URL Parameter name>");

Thanks for taking the time to answer my question.
I have the main html file and all other files needed by the main file in one directory on the application layer of SAP. I'd like to provide the user with a link, by clicking on which they should be able to get to the main html file using the browser. This is just a standalone application.
I can try the approach using BSPs, however, I'm new to that area. Could you point me in the right direction to get started?
