Force use of Model Node

Hello All,
I was wondering whether there is a way to force users to become a model
node in a given environment rather than give them the choice of specifying
model node or an individual node name. What happens is that our
developers, all on the same identical platform and setup, at one time or
another log in with their machine name as the node name and we end up with
tons of nodes in the environment which slows everything down (according to
Forte).
If we could just turn off that option for clients and force the use of a
model node depending on platform that would be great.
Thanks in advance for any info!
Sincerely,

Is anybody using MODEL in production?
How is the performance - is there any real problems?I used a MODEL query last year to simulate a FIFO queue and calculate average stock prices.
It performs pretty well, but the volume of data is small though (~200k rows processed per batch session).

Setting max length of the field when using Context Model Node

I have created a model using Import Adaptive Web Service model option (a web service was a wrapper around SAP BAPI function module).
There were no dictionary types created in the Local dictionary as a result of import.
I have mapped the context of the controller to the model node.
One of the fields in the model is name CUSTOMER_NUMBER type string;
Corresponding element in the wsdl of the web service is
<xsd:element name="CUSTOMER_NUMBER" type="tns:char10" />
I have created a view with the input filed mapped to the CUSTOMER_NUMBER field of the model node.
When I type more than 10 chars into the field and hit the search button, I get a com.sap.dictionary.runtime.Ddcheck exception that the length of the field should be less than 10 chars.
How can I set the max length of the field in design time to prevent runtime exception?
Thanks,
Julia

Thank you for your reply.
Java trim function will trim the white spaces only, not the characters.
I can code check length functionality before calling execute function (the function that call the web service).
I can also create a dictionary structure based on the model structure; create a context value node based on the dictionary structure and use WDCopyService API to move the data between value node and model node.
I was looking for the best practice...
When importing model based on Adaptive RFC, the dictionary structures are imported together with the model. This does not happen for Adaptive web service - hence there is a need to add coding for simple checks.

CRM model nodes

Hi
I am new to weclient ui and i want to know how to use a model node. I have created a simple object in spro which is my ztable. so now, will i be able to acess the data in my ztable just by creating a model or do i need to any extra coding to get data from BOL to the component controler's comtext. I need a detailed solution pls, i have very basic knowledge of these things

Hi
I saw the article and created a model node ZCRMBOL in component controller and view controller. I then bound both the nodes and tested it gave exceptions ..... i have a simple object ZCRM_BOL in root objects of BOL_BROWSER, and i have created model node ZCRMBOL with that BOL Entity.I have created ZCRM_BOLSearch object as well. The error that i am getting in the browser while testing is -

[Model Nodes] What prevents Server Parts to be assignedthere ?!:?

Hi,
I want to have a separate node to provide a dedicated service,
and therefore when I start my environment server and declared that
node as ModelNode, with 'client' disabled, i still can't assign to it
my server partition.
And if I declare it as regular node, the installation of the application
failed if the node is not online.
What choice do I have ?
What prevents that ModelNode, client disabled, to host server partition ?!,

Jean-Paul,
The ModelNode is a client node by definiton, no matter what properties you
change. I've previously asked for an enhancement to allow a
model node to be a
server node, but I don't expect much to happen. To install
server applications
to several nodes, you have to make sure that the node manager on
each node is
active. There really is no built-in support for distributing
applications in
mass to servers like there is for clients (using the model node feature).

Creation of new element in Model Node

Dear All,
I am facing one problem, I have two model node. I want to copy one model node to other model node.while copying its giving error saying the you can bind the element, coz target node doesn't have valid parent.
Pl don't suggest me work on Value node.
Can i create a element in model node at run time.
Thanks & Regards
Manoj Sahoo

Hi Manoj,
Model node properties :
1.A context model node makes a model object look like any other context node. I.E. it gives the model object an API that is very similar to a value node.
2. A model node is not considered valid until it is bound to a corresponding model object. Therefore, a model node always inherits its metadata from the model object to which it is bound.
3. The element collection in a model node does not hold the actual runtime data! Instead, it holds a list of references to the relevant model object instances.
If u check the 2nd property, u will find the cause of ur exception. As u have already told, don't suggest to use value nodes, i don't have any other comment.

Sumit

Need help to read model node input field attribute present in view - first time developer.

Hello Experts,
I am new to CRM Web UI development.
Presently, I am trying to develop a Guided Activity Page having 2 views.
First view has the field Business Partner Number, I have added model Node BuilHeader and the attribute BP_NUMBER while creation of the view.
The Second View consists of 2 fields from the Model Node BuilHeader, namely First Name and Last Name.
The requirement is to enter the BP Number on the first screen then click on the NEXT button from the Guided Activity buttons, on navigating to the Second View, the Names should auto-populate.
I have Created both views and the GP page, the GP navigation is also happening. Initially the fields were showing Not Bound text in value, so I commented the line in GET_I and GET methods to enable the field and remove the Not Bound text. I have created a custom controller with BuilHeader
I have tried doing this but facing the below problems :
1) When I enter the BP number on the first view and press Enter, the value disappears. How to solve this ?
2) Does clicking on the NEXT button on the GP Navigation trigger a Server Roundtrip ?
3) How to read the context node value of BP Number entered on the first view and populate the Name fields on the second view.
Please help.........

you can take reference from from below code as in above case we use BuilHeaderAdvancedSearch search object, to get current entity.
data: query TYPE REF TO cl_crm_bol_dquery_service,.
query ?= me->typed_context->BuilHeaderAdvancedSearch->collection_wrapper->get_current( ).
Do not remove code from getter setter of fields , it will not clear.
Check with http://scn.sap.com/thread/3391203 , for basic understanding of UI.

How can I create a model node in SAP Records Management

Product: SAP Records Management
Hi,
I would like to create a model node in a record tree.
I found in the function modul BAPI_RECORD_ADDELEMENT no entry for the creation of a model node. Only the instance and the structure node can create by this function modul.
So, does anyone know a solution to create a model note?
Regards,
Thomas Fanninger

Hi Thomas,
it is not possible with the BAPI due to the piece of coding:
case myElementType.
        when glob_const_elem_type_instance.
          myRecordElement->Type_Set( if_srm_sp_record_element=>type_instance ).
          myRecordInstanceElement ?= myRecordElement.
          loop at element_sp_poid into myElementSpPoidWa.
            mySpPoidWa-id = myElementSpPoidWa-name.
            mySpPoidWa-value = myElementSpPoidWa-value.
            insert mySpPoidWa into table myElementSpPoidTab.
          endloop.
          myElementSpsId = sps_id.
          myElementPoid = myClientService->poid_get_instance( im_rms_id = myRmsId
            im_sps_id = myElementSpsId im_sp_poid = myElementSpPoidTab ).
          myService->check_sp_connection( myElementPoid ).
          myRecordInstanceElement->poid_set( myElementPoid ).
        when glob_const_elem_type_folder.
          myRecordElement->Type_Set( if_srm_sp_record_element=>type_folder ).
        when others.
          perform set_error using '852' return.
          return.
      endcase.
But you can do that by using directly the Records API. How to use this is demonstrated in the report 'SRM_RECORD_API_HOWTO'. Search there for the subroutine 'fillrecordelement'. There a record element for insert is created and its type is set. You can set the type there to 'IF_SRM_SP_RECORD_ELEMENT~TYPE_MODEL'. Of course your POID then may not be an instance POID.
Best regards,
Thomas

How to get the data from the model node like a table ?

I want to get the data from the model node once a record ,and the node is bound to a internal table in the RFM which I called in the R/3 system. Who can give me some advice to achive it?Thank you!!

Hi,
To get the data from the node:
wdContext.node[your node name].current[node name]_InputElement().get[specific element in the node];
or you van use:
wdContext.current[your node]Element().get[your element in the node];
examples:
wdContext.nodeZ_Mepro_Po_Detail_Stock_Distri_Input().currentZ_Mepro_Po_Detail_Stock_Distri_InputElement().getUcpd_Flag();
wdContext.currentT_Delv_ReqsElement().getShelflife();

Difference among Model node creation, model attribute creation and the field creation in database through AET?

Hello Friends,
To display the field on the View, we can create the field via 3 ways:
1) By creating the model attribute
2) By creating the model node using the GENIL object and using its attributes in view
3) Creating the field in Database structure using AET
But, i am not aware that in exactly what kind of business scenarios we use the above 3 methods to create the field.
Could you help me out to clarify the same.

Hi Dev,
1). By creating the model attribute: we will use this option in case of the field is avaibla in stanadrd sap system. It might be in another under child context nodes and we will use BOL relations to access the attribute.
2). By creating the model node using the GENIL object and using its attributes in view: We will use this option incase of there is no standard provision to use. Means you want to create any custom assignment block with custom attributes then you can go for this option. More over we can use AET to create custom genil object. We have an option Create Table in AET.
3).Creating the field in Database structure using AET: We will use this option incase of there is no attribute in database relevant to your requirement then we will go for AET enhancement.
Hope this might give you little clarification..

Dharmakasi.

Problem in mapping model node with cardinality

Hi,
I have a requirement where the RFC which is being called has cradinality 0..n.
I imported the RFC model in a different DC and then added the model to public part.
Then, I used that model in the second dc.
Now, I did context mapping with the component controlller by dragging the model context to the
component controller. The view is also mapped with the component controller.
The RFC has input field BUS_PART_NO which is a 12 character input field.
I passed String in it.
There is no error while I build the DC. But while I run the application, the input field is coming Read Only.
I can't changed the component controller to 1..n or 1...1.
I think I need to create a context node and attribute in the view or component controller and then programmatically add this
to the model node.
Please send some SDN links and urls.
Regards
Neha Singh

Hi Neha,
Please create the custom context node/attribute same structure as RFC model node. then populate the data using below following code :
- get the size of the RFC model node which you want to populate in the costom node like
int xxx = wdContext.node<XXX node>().size;
- Create onject for custom node like
I<Custyom Name>Element element = null;
- then use for loop for fetching data from Model node and populate in custom node
for(int i =0; i<xxx; i++)
         element = wdContext.create<Custyom Name>();
         element.set<Attribute Name>(wdContext.node<XXX>().get<XXX>ElementAt(i).get<>Attribute name for model())
         wdContext.<Custyom Name>().addElement(element);
It will populate in your custom node from model node.
Hope it will helps you.

Populate model node with an internal table

Dear experts
I have an internal table. I have a model node. I need to populate the data in my internal table onto my model node.
In case of a value node, I know how to do this.
I would appreciate if somebody can give me some 'code snippet' on how to do this in case of a model node.
I tried looking into some standard components but its bit confusing.
Any replies will be greatly appreciated.
Thanks in advance.
Raj

Hi Masood
Thanks for the reply. Actually I am familiar with using the method 'set_properties'. But my main confusion is on how to create an instance before calling this 'set_properties' method.
For eg: in case of value node, we will use
FIRST CREATE OBJECT
create object lv_value_node
exporting = ls_struct
THEN SET THE PROPERTY
lv_value_node->set_propety ( ).
But in the case of model node, I wont be able to use the statement
"create object lv_model_node
exporting = ls_struct"
So I need to create an instance of the BOL. This is where I am confused. And my BOL is FUSearchRes. It is a 'Search Result object' in Genil_model_browser. So I cannot create a root object. Also I don't see any parent for this.
So I am not sure of how to create objects for this particular BOL. Plz throw some light on this.
Thanks
Raj

Mapping Model Nodes

Hi Gurus,
Can anybody tell me , which is the best practise for mapping a structure to view through Component Controller .
1) Setting all the model node values to a Value node on controller level and Map to the view
2) Directly mapping the model node from controller to View .
Please tell me the advantage also ?
Thanks in advance .
Tony Isaac.

Hi Tony,
This looks quite wiered. As far as I think EHP1 should not restrict you to bind any modeled node attribute with the UI element. This is very basic requirement and as I said earlier if the scenario demands then we always bind teh values directly to the UI element.
It makes no sence in first copying the values of the modeled node to the value node and then used the value nodes and finally take the values of the value node, copy them back to modeled node and finally save it. It will definitely hinder the performance. And in scenariois where we have lot of attributes in the structure then in all such cases the performance will be decresed drastically.
Therefore I dont feel that there will be any such restriction on this.
I hope this helps!
Thanks and Regards
Pravesh

Problems in Instantiating the Model Node

Hi All,
I Have a problem with creating the instance of a Model Node which needs an urgent solution, This is the Scenario:
I Have created a WebDynpro Project using NetWeaver CE Environment and Java EE 5.0 where i am using an Adaptive WebService Model. I have successfully created the model using the WSDL files and have also added to the Controller,
But when I try to create an Instance of the Request Node in my controller ie after writing this line:
Request_MI_Nwce007_AS_SOAPReq objReq = null;
objReq = new Request_MI_Nwce007_AS_SOAPReq();
This is the Request Structure from the WSDL - Request_MI_Nwce007_AS_SOAPReq
it gives me an Error saying The constructor Request_MI_Nwce007_AS_SOAPReq() is undefined.
Please let me know the exact problem and also the way to overcome this problem.
Its Quite URGENT!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Points Rewarded for helpful answers.
Regards,
Poojith MV

Hi Poojitha,
If your imported Webservice has any structure like this Request_MI_Nwce007_AS_SOAPReq_Input then instantiate the input structure.
else
Try instantiating along with the package name, for example if your package name is: com.sdn then try this:
"com.sdn.*Request_MI_Nwce007_AS_SOAPReq objReq = null;
objReq = new com.sdn.Request_MI_Nwce007_AS_SOAPReq();
Hope this solves your problem.
Thanks n Regards,

---ModelNode_Response
i tried with the below code but effort went in vain.
i tried following ways to set the value but , i get Nullpointer expection error.
     wdContext.nodeRequest__SubmitRequest().nodeRequestDetails().nodeRoles().
          currentRolesElement().setRoleId("BASIC");
     wdContext.nodeRequest__SubmitRequest().nodeRequestDetails().nodeRoles().
          currentRolesElement().setSysId("R3_220");
i aslo looked into the forum https://www.sdn.sap.com/irj/scn/thread?messageID=2035342 but couldnt find any solid solution.
It would be great if some one can throw some snippets on the same.
Thanks

Hi RR,
As far as i know u can set model nodes and values nodes are different. whats shown in the link is for values node. u should do differently for model node..
    Since this is a model node...u first need to create an object of the node type. then create an arraylist for that and then add values..
try this..
// Create an object for structures in the node to be used
Yweb_Po_Items objPOItems = null; // where Yweb_Po_Items is the structure of the node...
// Create an abstractlist for structures in the RFC node to be used, if u are planning to give single or multiple rows (in node/table) as input to the RFC
AbstractList POObjAbsList = new Yweb_Po_Items.Yweb_Po_Items_List();
objPOItems = new Yweb_Po_Items();
//    /set first set of values
objPOItems.setColumn1(u201Cabcu201D); // here hard codede for example
objPOItems.setColumn2(u201Cabcfghu201D);
// add the object to the abstract list
POObjAbsList.add(objPOItems);
//    /set second set of values
objPOItems.setColumn1(u201Cnewabcu201D);
objPOItems.setColumn2(u201Cnewabcfghu201D);
// add the object to the abstract list again
POObjAbsList.add(objPOItems); // now u got 2 records
// now set the abstractlist to the node in the RFC
objGoodsReceiptPO.setPo_Items_In(POObjAbsList);
Hope this information is useful...
Thanks
