Drop-Down WebDynPro components - Poor Performance ( MSS )

Hello everyone,
I am currently working with a customer who is implementing ESS/MSS on NW2004s with an ECC 6.0 backend.
We are having pretty poor performance with the DropDown UI components in the DynPro iViews. Sometimes they take upto 5secs to appear. ( which is annoying ) I have verified that the performance impact is due to machine performance ( too much javascript going on ) and the normal calls to the backend to populate the dropdowns.
My question is if there is anyway to 'pre-populate' the dropdowns when the iView is loaded and turn off the live calls to the backend when they are clicked. ( We cannot do anything about the machine performance )
Thanks

why dont you use node and save all the drop down attributes in it before loading that screen itself?
This may help you to avoid consuming such time during populating dropdowns.
create a node.
save all the drop down elelments to it in an attribute and it will not take so much of time to populate as it will be already present before runtime.

Error Deploying ESS/MSS ERP2005 WebDynpro Components for SP7

Hi,
I have been in process of trying to Patch up the J2EE stack in an attempt to turn on SAP Delivered Solution for ESS/MSS.
We are on EP7 with ECC6 Backend.
What I have done so far::
1. Updated J2EE with Netweaver SP stack 11.
2. Imported the business package for ESS/MSS into EP. I can confirm that the content is now available on PCD.
3. Then i tried to upload the WebDynpro Components for ESS/MSS. Files are PCUI_GP, ESS and MSS. they all have a named reference to 600 SP7. These are the ones available to download for self-services from mySAPERP components on service market place.
This step is now falling over. Deployment of these components fail when its trying to deploy the application component. I must add that once we loaded the Business packages for ESS/MSS (step 2), i then checked the delivered content and created a delta link to the AU/Address iView into my own content folder. I am not sure if this has anything to do with the Failure of deployment but this is the only thing that i did in between steps 2 and step 3.
I didn't think that it would have caused any issue as this was an iview while the component its trying to deploy is a webdynpro application, but i am not sure now.
Please see the trace below.

Hi Friends,
I got the same problem but not on ESS/MSS component. But the exception was exactly the same. The solution what i found is
1. Find the exception in the Default trace. By searching for DC Name.
2. Here you should find the one in which its mentioned below error
com.sap.tc.webdynpro.repository.RepositoryRuntimeException: Failed to deploy the file '/usr/sap/EPD/JC35/j2ee/cluster/server0/./temp/webdynpro/public/burton.com/portal~passwordchange/webdynpro/Components/com.burton.webshop.b2b.myprofile.EditPassword/EditPassword.xml' into the database. Reason: Development Object 'local/wdMyProfile' contains already same repository content. Hint: fully qualified name of the repository VMO must be globally unique.
3. Now go to the visual administrator -> deploy -> webdynpro and undeploy the local webdynpro with which the current DC is conflicting. (You should decide whehter you can undeploy or not)
4. Now try activate the activity or Deploy the DC you shouldnt get the problem.
Actually i got this problem when i created a WebDynpro DC by importing the local webdynpro project. So, when i try to activate the activity of DC created then its not getting deployed. When i check the logs, i had same exceptions as you ppl got. So after going thru default trace then i figured out that the local webdynpro is the reason for this conflicting. Then i undeployed that webynpro.
Hope this may be useful for you and others...
Thanks,

Triggering "exit" event of a drop-down list in all instances of a table row

I have a drop-down list in a table row with multiple instances that performs a calculation on the exit event. This calculation draws information from 2 other dropdown lists contained above in non-repeating rows of the same table.
The desired behavior is: should the user change their choices above, all instances of the drop-down list below would perform the "Exit" event script accessing the new values above.
My script is:
RowOptionalCoverage.DdlCoverageType.execEvent("exit");     this works, sort of
It only updates the first instance of RowOptionalCoverage and none of the subsequent instances. The user can "Tab" through the instances and trigger the Exit event for each instance, but this is not a reasonable solution.
I have tried using the resolveNodes method without success. I understand, using the resolveNodes method may be necessary when referencing multiple instances of an object:
this.resolveNodes("RowOptionalCoverage[*].DdlCoverageType[*]").execEvent("exit");     doesn't work
xfa.resolveNodes("RowOptionalCoverage[*].DdlCoverageType[*]").execEvent("exit");      doesn't work
No doubt, I must be using the resolveNodes incorrectly or missing something? Probably something simple.
Any advice is greatly appreciated.

PERFECT!!! Works right out of the box!
This has opened my eyes to the essential nature of loops. My form is very large and complex and functions correctly, Yet the coding is lacking in sophistication--no loops, functions, fragments or other code efficiencies. I am teaching myself (with the help here) and I have skipped learning and using some techniques when I could things to work using the limited skill set I have.
Sometimes, I just don't "get it". After I fail a few times, I skip it and try something else. Functions are a great example. I could utilize a bunch of these if I could only write one that works. It is frustrating. If I got one to work, I know could write a ton of them. But, there is some essential part of functions I am missing that's preventing me from having my first success with them. (I think it has to do with not understanding arguments completely).
Anyway, I am overjoyed with the solution you provided and I understand it well enough to be able to use again in other situations.
Thanks again!

Creating drop down menus

Since Flash catalyst does not have a drop down component, does any one know how to create one.
For example a horizontal menu you get in a application?
Would be most grateful for any advice.
Regards
Josh.

Hi Chris
I have created the first custom combo box which has a button and a datalist. This show's my file drop down menu. Now I want to create custom components for each menu item: Edit menu, View menu and so on... that will be a total of 9 custom drop down menu components. Is it now possible to put all these components within another custom component to create a navigation bar, for eaxmple the Microsoft word top menu?
Then with the datalist items in each component transitions to a state to show content in the main window.
Is it possible to do this interface in Flash catalyst.
Regards
Josh.

Poor performance when using drop down box on web report

We are using dropdown box functionality in web reporting to allow easy selection of characteristics values. We have 4 dropdown boxes
that represents Region, Area, Country and division.
We need to use booked_values = 'Q' to show only relevant values for selection in the dropdown. However the issue is takes a long time for results to appear
on the template. Read from Fact table is quick but process of deriving drop down values is very slow.
<object>
         <param name="OWNER" value="SAP_BW"/>
         <param name="CMD" value="GET_ITEM"/>
         <param name="NAME" value="DROPDOWNBOX_1"/>
         <param name="ITEM_CLASS" value="CL_RSR_WWW_ITEM_FILTER_DDOWN"/>
         <param name="DATA_PROVIDER" value="DATAPROVIDER_1"/>
         <param name="BORDER_STYLE" value="BORDER"/>
         <param name="GENERATE_CAPTION" value=""/>
         <param name="IOBJNM" value="ZPC_ORG14"/>
         <param name="BOOKED_VALUES" value="Q"/>
         <param name="TARGET_DATA_PROVIDER_1" value="DATAPROVIDER_1"/>
         ITEM:            DROPDOWNBOX_1
</object>
Do you have any suggestions on how to improve performance on drop down?
Thanks, Jay

Dear Jayant Dixit,
1) If the values in the drop down box....are NOT dependent on user selection...then webserver can send them along with the first page....and cache them on client m/c...for multiple client/server dialogs....
2) If the values are changing based on what the user selected from a previous input......then...you need to do some research on how SAP Webserver could optimize the "network traffic"......For example: a) Apache webserver has a module that compresses the content on the webserver side and then send to the client...b)A Client browser plugin decompresses the received packet and displays appropriately....
3) We may need to research the latest SAP webserver capabilities....
Good luck, BB

Poor performance with WebI and BW hierarchy drill-down...

Hi
We are currently implementing a large HR solution with BW as backend
and WebI and Xcelcius as frontend. As part of this we are experiencing
very poor performance when doing drill-down in WebI on a BW hierarchy.
In general we are experiencing ok performance during selection of data
and traditional WebI filtering - however when using the BW hierarchy
for navigation within WebI, response times are significantly increasing.
The general solution setup are as follows:
1) Business Content version of the personnel administration
infoprovider - 0PA_C01. The Infoprovider contains 30.000 records
2) Multiprovider to act as semantic Data Mart layer in BW.
3) Bex Query to act as Data Mart Query and metadata exchange for BOE.
All key figure restrictions and calculations are done in this Data Mart
Query.
4) Traditionel BO OLAP universe 1:1 mapped to Bex Data Mart query. No
calculations etc. are done in the universe.
5) WebI report with limited objects included in the WebI query.
As we are aware that performance is an very subjective issues we have
created several case scenarios with different dataset sizes, various
filter criteria's and modeling techniques in BW.
Furthermore we have tried to apply various traditional BW performance
tuning techniques including aggregates, physical partitioning and pre-
calculation - all without any luck (pre-calculation doesn't seem to
work at all as WebI apparently isn't using the BW OLAP cache).
In general the best result we can get is with a completely stripped WebI report without any variables etc.
and a total dataset of 1000 records transferred to WebI. Even in this scenario we can't get
each navigational step (when using drill-down on Organizational Unit
hierarchy - 0ORGUNIT) to perform faster than minimum 15-20 seconds per.
navigational step.
That is each navigational step takes 15-20 seconds
with only 1000 records in the WebI cache when using drill-down on org.
unit hierachy !!.
Running the same Bex query from Bex Analyzer with a full dataset of
30.000 records on lowest level of detail returns a threshold of 1-2
seconds pr. navigational step thus eliminating that this should be a BW
modeling issue.
As our productive scenario obviously involves a far larger dataset as
well as separate data from CATS and PT infoproviders we are very
worried if we will ever be able to utilize hierarchy drill-down from
WebI ?.
The question is as such if there are any known performance issues
related to the use of BW hierarchy drill-down from WebI and if so are
there any ways to get around them ?.
As an alternative we are currently considering changing our reporting
strategy by creating several higher aggregated reports to avoid
hierarchy navigation at all. However we still need to support specific
division and their need to navigate the WebI dataset without
limitations which makes this issue critical.
Hope that you are able to help.
Thanks in advance
/Frank
Edited by: Mads Frank on Feb 1, 2010 9:41 PM

Hi Henry, thank you for your suggestions although i´m not agree with you that 20 seconds is pretty good for that navigation step. The same query executed with BEx Analyzer takes only 1-2 seconds to do the drill down.
Actions
suppress unassigned nodes in RSH1: Magic!! This was the main problem!!
tick use structure elements in RSRT: Done it.
enable query stripping in WebI: Done it.
upgrade your BW to SP09: Has the SP09 some inprovements in relation to this point ?
use more runtime query filters. : Not possible. Very simple query.
Others:
RSRT combination H-1-3-3-1 (Expand nodes/Permanent Cache BLOB)
Uncheck prelimirary Hierarchy presentation in Query. only selected.
Check "Use query drill" in webi properties.
Sorry for this mixed message but when i was answering i tryied what you suggest in relation with supress unassigned nodes and it works perfectly. This is what is cusing the bottleneck!! incredible...
Thanks a lot

OnSelect event for a Drop down UI Element in Webdynpro ABAP Select Options

Hi Experts
We have built our UI based on the webdynpro ABAP Select Options. We have a requirement that, when we change the value of a drop down box in the UI, I need to hide some fields. Can anybody help me out in handling of OnSelect event of a drop down box built using webdynpro ABAP Select Options. We are on SAP Netweaver 7.0 EHP1.
Rrgards,
Srikanth.
Edited by: Srikanth Kancherla on Apr 29, 2010 10:43 PM

Hi Srikanth,
as you seem to be already aware, the component is dynamically built.
so you would have to enhance the code that builds the element and insert a reference to a new action (enhancement) that could handle the onSelect event.
What is it about this that you particularly want help with?
Cheers,
Chris

How can I add values on a Drop Down by Index Webdynpro Element?

Hi every body
Can anybody help me?
How can I add values on a Drop Down by Index Webdynpro Element?
How can I invoque my element on the Implementation Webdynpro?

Hi Jesus,
You can add elements to your DDbyIndex like this:
//Example: Popular un Dropdown by Index usando Nodos de contexto
// NODE[Card: 1..n, Sele:1..1] Si es obligatorio;            ||    NODE[Card: 0..n, Sele:0..1] Si no es obligatorio y se puede dejar en blanco
//Assuming we created a node called "Source", with a string attribute called "Texto" binded to the dropdownbyindex
for (int i = 1; i <= 101; i++)
     ISourceElement sourceElement = wdContext.createSourceElement();
     sourceElement.setTexto("Text number "+i);
     wdContext.nodeSource().addElement(sourceElement);

Webdynpro " How to add values in Drop down list By Key"

Hi experts ,
i want to create a drop down list by key, i don't know how to assign values to it ( i.e. add list entries ) . Please help me on this ..
With regards ,
James..
Valuable answers will be rewarded ....

Hi,
To fix values to the drop down key at runtime in the webdynpro application you can use the following code:
DATA:
lr_node_flightinfo TYPE REF TO if_wd_context_node,
lr_nodeinfo_flightinfo TYPE REF TO if_wd_context_node_info,
l_scarr type scarr,
lt_value_set TYPE TABLE OF wdr_context_attr_value,
lw_value_set like line of lt_value_set.
get nodeinfo of node flightinfo
lr_node_flightinfo = wd_context->get_child_node( name = 'FLIGHTINFO' ).
lr_nodeinfo_flightinfo = lr_node_flightinfo->get_node_info( ).
get value set (VALUE = CARRID , TEXT = CARRNAME)
select carrid carrname from scarr into table lt_value_set.
clear lw_value_set.
lw_value_set-value = 'AI'.
lw_value_set-text = 'Air India'.
append lw_value_set to lt_value_set.
sort the value set by the describing TEXT
SORT lt_value_set BY text.
set value to context attribute
lr_nodeinfo_flightinfo->set_attribute_value_set(
name = 'CARRID' value_set = lt_value_set ).
Here CARRID is a drop down by key field on the screen.
in The context it is an attribute in the node FLIGHTINFO.
Please give Reward Points if this piece of code helps

Thanks...
Edited by: Rakshar on Sep 12, 2011 7:30 AM

Hi Rakshar,
1. Add an onSelect event to the Dropdown 1.
2. In the event handler get the the selected value of Dropdown 1 from the context of the same. Based on the selected value, retrieve the data to be displayed in Dropdown 2 ( for example data from a table)
3. Invalidate the context for Dropdown 2
4. Bind the data retrieved from table to the context for Dropdown 2 by using method BIND_TABLE
Let me know if you face any difficulty.

Drop down by index in webdynpro

I am using a drop down by index element in my webdynpro ABAP screen.
I populate this drop down by fetching values through a remote-enabled function module. How do i set one particular value as default after fetching these values. ?
I am getting the currency keys as the list of values and want to show a particular value when the view is first shown. How is this possible?
regards,
Priyank

Hi Priyank,
    I have the sample code where index is used.
    This code is used for radiobutton group by index.
    You can use same logic in your requirement.
data:
    text    type string,
    element type ref to if_wd_context_element,
    index   type string.
DATA:
    node_check                          TYPE REF TO if_wd_context_node,
    elem_check                          TYPE REF TO if_wd_context_element,
    stru_check                          TYPE if_start_ior=>element_check ,
    item_check_attribute                LIKE stru_check-check_attribute.
element = wd_context->get_lead_selection( ).
index = wdevent->get_string( 'INDEX' ).
Case when Overhead option is selected
navigate from <CONTEXT> to <CHECK> via lead selection
node_check = wd_context->get_child_node( name = if_start_ior=>wdctx_check ).
get element via lead selection
elem_check = node_check->get_element( ).
get single attribute
elem_check->get_attribute(
    EXPORTING
      name = `CHECK_ATTRIBUTE`
    IMPORTING
      value = item_check_attribute ).
if index EQ 2.
elem_check->set_attribute( name = 'CHECK_ATTRIBUTE' value = Abap_true ).
endif.
if index EQ 1.
elem_check->set_attribute( name = 'CHECK_ATTRIBUTE' value = Abap_false ).
endif.
Hope this answer will help you.

Im new in Webdynpro ABAP, my requirement is to fill drop down list in adobe interactive form. i created adobe form and its working fine.

Webdynpro for ABAP - interactive Adobe form - drop down lists not working

Hi all,
I'm trying to create an interactive form for a client using webdynpro for ABAP and I've viewed the demo "Create SAP Interactive Forms by Adobe with Web Dynpro for ABAP" by Thomas Jung, but when I implement it the form following similar steps the form is not interactive.
In the properties of the "InterativeForm", I've tried clicking the "enabled" flag both on and off. I've also tried setting the "displayType" property to both "ActiveX" and "Native". But none of this worked.
I though my problem might be with Adobe reader so I switched from 8.0 back to 7.0 but this didn't make any difference either.
The system we are using is NW04s WAS 700. Any hints would be greatly appreciated!
Thanks,
-tom

Thanks for the suggestion Dezso. I've downloaded a newer version of ACF as indicated by the OSS note and installed it. I'm still having the same issue.
My basic question is what options should I be using in the form and on the InteractiveForm component? It looks like because of the evolution of the product there are multiple options available. I recall reading somewhere that as of a certain SP level we should have ZCI (zero client install) available. The would be our preference. It will be a support nightmare if each user needed a manual download of ACF.exe installed.
Should I click the "enabled" flag on the InteractiveForm object? When I create the form should I use the "Native" drop down list or the one from the "Active X" tab? I would like to use the "List Box" control on the form as well but it is only available in the "Standard" tab. So does that mean I can't get the selections from a "List Box"?
Thanks,-tom

[Forum FAQ] The Value drop down list is grayed out when you perform search for Group Policy Objects in GPMC

Symptom
On Windows Server 2012 or Windows Server 2012 R2, when you use the Search for Group Policy Objects feature in GPMC, the “Value” field is not populated when you choose “User Configuration” as the Search Item. (See Figure 1.)
<Figure 1>
Cause
The happens because the Data of the (Default) value of the following Registry Key is not correct.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions\{4D2F9B6F-1E52-4711-A382-6A8B1A003DE6}]
By default the Data is (value not set). (see Figure 2)
<Figure 2>
Resolution
The registry keys under [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions] are the Group Policy Preference Client Side Extensions. The CSE name of the GUID {4D2F9B6F-1E52-4711-A382-6A8B1A003DE6} is
RemoteApp and Desktop Connections. Please follow the steps below to resolve the issue.
1. Locate the registry key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions\{4D2F9B6F-1E52-4711-A382-6A8B1A003DE6}]
2. Take the ownership of this key: Right click on the registry key and choose Permissions option and click the Advanced button on the dialogue window. Then on the Advanced Security Settings dialogue window, click Change button to take the ownership
of the key for the current logon account and make the current logon account Full Control permission with the registry key. (See Figure 3.)
<Figure 3>
3. Change the data of (Default) value from "(value not set)" to
"RemoteApp and Desktop Connection Component". (See Figure 4)
<Figure 4>
4. Once the steps above are completed, the Value drop down list will be populated again when you perform Search in GPMC. (See Figure 5)
