Calling a BW Bex Query in Web Dynpro ABAP

Question

Hi Team,
I'm trying to call a BW Bex query in my web dynpro screen. The Web Dynpro is written in our ERP (ECC 6.0) system. I have specific parameters and values in my web dynpro context which I want to pass to a BW query and then display the actual query in my web dynpro. I found an element BIApplicationFrame but don't know if that is the correct way to display the query. Some questions:
1) How do I pass the username/password for the BW system in the Web Dynpro written in ERP?
2) How do I pass the parameters to the query
3) How is the security and roles managed. The web dynpro is enables as an iView in the SAP Portal.
Thanks much for your guidance.
Regards
Sanjay

Petr:
I managed to pass the selection variables to the query through BIApplicationFrame. This is how I did it.
1) Added the BIApplicationFrame UI element to the View of the Webdynpro application and named it ZBIQUERY with the following properties relevant to my system.
- dataProviderStateName property is set to my query name which is 'ZPUR_M02_Q08'
- dataProviderStateType is set to 'Query'.
- server is set to 'housapdbw.noble.cc:8000'
- templateId is set to 'ZPUR_M02_W02'
- variableScreen is Unchecked.
2) Added two attributes to the view under the attributes tab. They are
M_APPL_FRAME RefTo CL_WD_BIAPPLICATION_FRAME
M_METHOD_HANDLER RefTo IF_WD_BI_APPLFRAME_METHOD_HNDL
3) Then add the following code in the method WDDOMODIFYVIEW.
data:
lt_parameters type if_wd_bi_applframe_method_hndl=>tt_name_value,
ls_parameters type if_wd_bi_applframe_method_hndl=>t_name_value.
define add_parameter.
clear ls_parameters.
ls_parameters-name = &1.
ls_parameters-value = &2.
append ls_parameters to lt_parameters.
end-of-definition.
if first_time = abap_true.
wd_this->m_appl_frame ?= view->get_element( 'ZBIQUERY' ).
wd_this->m_method_handler ?= wd_this->m_appl_frame->_method_handler.
endif.
Please note that the selection screen on my query has Select-options and its name is
XREF_NUM0001. I am passing a value of '11111' to it as shown below.
refresh lt_parameters.
add_parameter 'CMD' 'PROCESS_VARIABLES'. " This is for Execute button
add_parameter 'SUBCMD' 'VAR_SUBMIT'. " This one also for Execute Button
add_parameter 'VAR_NAME_1' 'XREF_NUM0001'. " Name of my select-option
add_parameter 'VAR_OPERATOR_1' 'EQ'.
add_parameter 'VAR_SIGN_1' 'I'.
add_parameter 'VAR_VALUE_LOW_EXT_1' '11111'. " Value for my select-option
wd_this->m_method_handler->execute_command( lt_parameters ).
endif.
The above code needs to be added before the view is called in th is method.
Hope this helps.
