Need Quick help with InputNode OutputNode in OVS

[Former Member]

Hi there,

Can someone advise me what to do? This is what happen.

When I declared the inputNode and the outputNode for the OVS, I have specify the node directly 1 level above the fields that needs to be displayed in the OVS.

However, eg: I have only declared Get_Material as the inputNode and not the level above it, which is Request_Get_Material, and as a result, I could not use the command "execute" on Get_Material nodeElement.

Can someone advise me what I can do? I keep on getting execution error because of this I think. THANKS!!

Hi

Hi go to slide no. 10 of this doc [OVS|https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/user-interface-technology/wd%20java/wdjava%20archive/web%20dynpro%20valuehelp%20using%20object%20value%20selector.pdf]

and for execute follow [this|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/504540a4-fd0d-2a10-7c8e-c88289cf6457]

Thank you! I will refer to it, however the 2nd pdf does not talk about "execute" at all.

Hmmm I was wondering what do I look out for when executing the "execute" for the model? It is really puzzling.. I have different functions which are very similiar and I have bind and instantiate all the necessary input, however, some of them will give error like:

com.sap.tc.webdynpro.model.webservice.api.WDWSModelExecuteException: Exception on execution of web service with WSDL URL 'http://j2eedevt:50000/DemoWebOrderWSMaterial/Config1?wsdl ' with operation 'Get_MaterialBySalesArea' in interface 'DemoWebOrderWSMaterial_Document'

when I tries to execute. The problem is it won't give any reason why the execution fail? They are so similiar execution but I wonder why do some of the fails while some works?

Hi

Do a little deep dive things will clear to u because I have done through those links only, or It might problem will a little different ,additionally I am giving code which I implemented.

public void onQuery(IWDNodeElement queryInputNodeElement, IWDNode queryOutputNode)

{

// Type Cast Input element

if (wdContext.currentOvsInputNodeElement().getUserId() == null)

{

wdThis.wdGetInstEjbInterface().executeGetAllUserMaster();

for (int i = 0; i < wdContext.nodeReturngetAllUserMaster().size(); i++)

{

IPublicOvsCustComp.IOvsOutputNodeElement ovsOutput = wdContext.createAndAddOvsOutputNodeElement();

IPublicOvsCustComp.IReturngetAllUserMasterElement modelOutput = wdContext.nodeReturngetAllUserMaster().getReturngetAllUserMasterElementAt(i);

ovsOutput.setFirstname(modelOutput.getFirstname());

ovsOutput.setLastname(modelOutput.getLastname());

ovsOutput.setEmailid(modelOutput.getEmailid());

ovsOutput.setGender(modelOutput.getGender());

ovsOutput.setUserid(modelOutput.getUserid());

ovsOutput.setRequestid(modelOutput.getRequestid());

ovsOutput.setMobile(modelOutput.getMobile());

}

} else if (wdContext.currentOvsInputNodeElement().getUserId() != null)

{

wdThis.wdGetInstEjbInterface().executeGetUserDetailsByUserId(wdContext.currentOvsInputNodeElement().getUserId());

for (int i = 0; i < wdContext.nodeReturngetUserDetailsByUserId().size(); i++)

{

IPublicOvsCustComp.IOvsOutputNodeElement ovsOutput = wdContext.createAndAddOvsOutputNodeElement();

WDCopyService.copyElements(wdContext.nodeReturngetUserDetailsByUserId(), wdContext.nodeOvsOutputNode());

// IPublicOvsCustComp.IReturngetUserDetailsByUserIdElement

// modelOutput1 =

// wdContext.nodeReturngetUserDetailsByUserId().get;

// ovsOutput.setFirstname(wdContext.nodeReturngetUserDetailsByUserId().get);

// ovsOutput.setLastname(modelOutput.getLastname());

// ovsOutput.setEmailid(modelOutput.getEmailid());

// ovsOutput.setGender(modelOutput.getGender());

// ovsOutput.setUserid(modelOutput.getUserid());

// ovsOutput.setRequestid(modelOutput.getRequestid());

// ovsOutput.setMobile(modelOutput.getMobile());

}

}

IPublicOvsCustComp.IOvsInputNodeElement custInputElm = (IPublicOvsCustComp.IOvsInputNodeElement) queryInputNodeElement;

// Type cast Output node

// IPublicOvsCustComp.IOvsOutputNodeElement custOutNode =

// (IPublicOvsCustComp.IOvsOutputNodeElement) queryOutputNode;

}

}

Revert ,if still unsolved?
