Model fails to get the new data from R3

[Former Member]

Hi All,

I am facing the issue with the new data comming from R3. I have some data in my view, I have to save those records in R3. I am doing the same, but I am failing to get the saved records comming from R3 when I refresh the page or application the new values are displaying.

Here are the steps I have followed to save the records

1) In wdDoInit of controller I am binding the model node

2) in execute method I am executing the "retrieve records bapi" to get the records

3)In view I am displaying those records. I have updated the records. I am calling "save records bapi" to save the records.

4) to refresh the new data again I am executing the "retrieve records bapi" method. But it is diplsaying the old data only.

My question is how to refresh the data comming from R3.

Hi,

When creating new RFC_input use WDModelScopeType.TASK_SCOPE in the constructor.

Hi,

Have you invalidated the nodes after recalling the RFC?

Hi,

Here is my code

1) code in wdDoInit

IWDComponent component = wdThis.wdGetAPI().getComponent();

try {

model = (ABC) WDModelFactory.getModelInstance(

ABC.class,

WDModelScopeType.TASK_SCOPE);

} catch (Exception e) {

}

wdContext.nodeSample_Bapi_Input().bind(

(Y_Sample_Bapi_Input) model.createModelObject( Y_Sample_Bapi_Input.class));

2) code in retrieve records method

IWDMessageManager manager = wdComponentAPI.getMessageManager();

try {

wdContext.currentSample_Bapi_InputElement().setI_Uname("user1");

wdContext.currentSample_Bapi_InputElement().modelObject().execute();

wdContext.nodeSample_Bapi_Output().invalidate();

wdContext.nodeSample_Bapi_Output().nodeTab_Data().invalidate();

} catch (WDDynamicRFCExecuteException e) {

manager.reportException(e.getMessage(), false);

}

3) code in save method

Y_Update_Sample_Bapi_Input input = new Y_Update_Sample_Bapi_Input();

wdContext.nodeUpdate_Sample_Input().bind(input);

IWDMessageManager manager = wdComponentAPI.getMessageManager();

try {

input.setI_Uname("user1");

input.setCountry(wdContext.currentSample_Bapi_Inputelement.getCountry());

input.execute();

wdContext.nodeUpdate_International_Output().invalidate();

wdContext.nodeUpdate_International_Output().nodeE_Return().invalidate();

}catch (WDDynamicRFCExecuteException e) {

manager.reportException(e.getMessage(), true);

}

I want to update the country. In my view I am displaying the countries in dropdown list, I can select country from the lsi I will update. When I refresh the page I am retrieve the updated country.

try the following coding:

1. in the other section

Y_Update_Sample_Bapi_Input RFCUpdate = new Y_Update_Sample_Bapi_Input(WDModelScopeType.TASK_SCOPE);

2. in wdDoInit

wdContext.nodeSample_Bapi_Input().bind(RFCUpdate);

3. In retrieve method

IWDMessageManager manager = wdComponentAPI.getMessageManager();
try {
RFCUpdate.setI_Uname("user1");
RFCUpdate.execute();
wdContext.nodeSample_Bapi_Output().invalidate();
wdContext.nodeSample_Bapi_Output().nodeTab_Data().invalidate(); 
} catch (WDDynamicRFCExecuteException e) {
manager.reportException(e.getMessage(), false);
}

4. In the save method

IWDMessageManager manager = wdComponentAPI.getMessageManager();

try {
RFCUpdate.setI_Uname("user1");
RFCUpdate.setCountry(wdContext.currentSample_Bapi_Inputelement.getCountry()); 
RFCUpdate.execute();
wdContext.nodeUpdate_International_Output().invalidate();
wdContext.nodeUpdate_International_Output().nodeE_Return().invalidate();
}catch (WDDynamicRFCExecuteException e) {
manager.reportException(e.getMessage(), true);
}
