Problem with DO_Dynamic_Navigation

[Former Member]

Hi friends,

I need to call the methods of another component and embed in my current component view container based on the embedding position.I called the method DO_DYNAMIC_NAVIGATION. when this method got executed it goes to the target component i.e where the required view exits,but it is unable to call the method.

it returns an error saying 'View V_OEL_STATS does not exist within the component /EMN/IHIS_QUANTITATIVE_CN.

where EMN/IHIS_QUANTITATIVE_CN is calling component,but the view is in EMN/IHIS_QUANTITATIVE.

I have put a break point in EMN/IHIS_QUANTITATIVE but it is unable to call the method V_OEL_STATS .

please help me in solving the below issue.

below is the sample code i have written.

DATA : node TYPE REF TO if_wd_context_node,

dl_api_main TYPE REF TO if_wd_view_controller,

l_nav_services TYPE REF TO if_wd_navigation_services,

LV_TARGET_COMPONENT TYPE STRING,

LV_TARGET_VIEW TYPE STRING,

LV_TARGET_PLUG TYPE STRING.

DATA lo_cmp_usage TYPE REF TO if_wd_component_usage.

lo_cmp_usage = wd_this->wd_cpuse_cu_quantitative( ).

IF lo_cmp_usage->has_active_component( ) IS INITIAL.

lo_cmp_usage->create_component( ).

ENDIF.

node = wd_context->get_child_node( 'ND_VIEWS_SWITCH' ).

node->set_lead_selection_index( index ).

CASE index.

WHEN '1'."assessment groups and agents.

LV_TARGET_COMPONENT = '/EMN/IHIS_QUANTITATIVE'.

LV_TARGET_VIEW = 'V_ASSESS_GROUP_AGENT'.

LV_TARGET_PLUG = 'IP_AGENTS'.

WHEN '2'."samples

LV_TARGET_COMPONENT = '/EMN/IHIS_QUANTITATIVE'.

LV_TARGET_VIEW = 'V_SAMPLE_SHEET'.

LV_TARGET_PLUG = 'IP_SAMPLES'.

WHEN '3'."sample results

LV_TARGET_COMPONENT = '/EMN/IHIS_QUANTITATIVE'.

LV_TARGET_VIEW = 'V_SAMPLE_RESULTS_SET'.

LV_TARGET_PLUG = 'IP_RESULTS'.

WHEN '4'."sample sets

LV_TARGET_COMPONENT = '/EMN/IHIS_QUANTITATIVE'.

LV_TARGET_VIEW = 'V_SAMPLE_RESULTS_SET'.

LV_TARGET_PLUG = 'IP_SETS'.

WHEN '5'."oel

LV_TARGET_COMPONENT = '/EMN/IHIS_QUANTITATIVE'.

LV_TARGET_VIEW = 'V_OEL_STATS'.

LV_TARGET_PLUG = 'IP_OEL'.

ENDCASE.

dl_api_main = wd_this->wd_get_api( ).

l_nav_services ?= dl_api_main.

l_nav_services->do_dynamic_navigation(

source_window_name = 'W_QUANTITATIVE_CN'

source_vusage_name = 'V_MAIN_USAGE_0'

source_plug_name = 'OP_QUAN'

target_component_name = LV_TARGET_COMPONENT

target_view_name = LV_TARGET_VIEW

target_plug_name = LV_TARGET_PLUG

target_embedding_position = 'V_MAIN/VCU_GENERIC' ).

Hi,

your code seems to me okay. I cannot validate the usage cu_quantitative to /EMN/IHIS_QUANTITATIVE.

can you check that as well. is the source_vusage_name also correct ?

have a look into this discussion [|]

Target_view_name should be the interfaceView name and not the actual view name itself.

Hi baskar,

Thanks for the reply,I have refered the thread which you have suggested.

for target_view_name i have passed the interface view name.( i am assuming that for each window a interface view is created),but in this window i have 4 to 5 views embedded.so it is calling all the views which are embedded in that view.

is it mandatory that each view has to embedded in a window so that it calls only the particular view when we pass the interface view name to method DO_DYNAMIC_NAVIGATION?

if that is the case I need to create Windows and assign each view to each window.

Hi,

No that is not mandatory. You have interface view and you have interface plugs which connects the respective view.

So in your case i would have expected W_OEL_STATS as your window name and IP_OEL is the interface plug in the window which connects to the window.

or target_view_name i have passed the interface view name.( i am assuming that for each window a interface view is created),but in this window i have 4 to 5 views embedded 

so please tell me what is your interfaceview name ? I see different names in your post. Make sure the plugs you fire are interface plugs .

hI BASKAR,

w_oel_stats is the interface view it is having 4 views. in this window ,i have created a plug called IP_OEL.I need to call a particular view V_OEL_STATS. How can I call that particular view.

WHEN '4'."oel

lv_target_component = '/EMN/IHIS_QUANTITATIVE'.

lv_target_view = 'W_IHIS_QUANTITATIVE'."'W_OEL_STATS'."'V_OEL_STATS'.

lv_target_plug = 'OP_OEL'.

ENDCASE.

dl_api_main = wd_this->wd_get_api( ).

l_nav_services ?= dl_api_main.

l_nav_services->do_dynamic_navigation(

source_window_name = 'W_QUANTITATIVE_CN'

source_vusage_name = 'V_MAIN_USAGE_0'

source_plug_name = lv_target_plug

target_component_name = lv_target_component

target_view_name = lv_target_view

target_plug_name = 'IP_OEL' IP_OEL is the plug created in interface view

target_embedding_position = 'V_MAIN/VCU_GENERIC' ).

in the window you need to connect the outbound plug IP_OEL to view V_OEL_STATS in bound plug.

>       lv_target_view      = 'W_IHIS_QUANTITATIVE'."'W_OEL_STATS'."'V_OEL_STATS'.

i do not understand this !! do you want to go to the nested interface view then? if not then change your statement

lv_target_view = 'W_OEL_STATS'
