Hi Lohitha,

Hi

Double click on the proxy classes created under 'Models', one of its property will be model data destination and you can change it there.

Similarly, for metadata destination, click on the dictionary created for that model (under dictionaries) and edit the property by that name.

Hi ,

thanks your response ,

I think this is statically change the single JCO.

Not the dynamic change.

Any other ideas.

Thanks

Hi,

You can set the client to be used dynamically. Use a code like this:

Let's say the name of your model is FetchListOfMaterials.

FetchListOfMaterials getModel = (FetchListOfMaterials)com.sap.tc.webdynpro.progmodel.model.api.WDModelFactory.getModelInstance(FetchListOfMaterials.class,WDModelScopeType.TASK_SCOPE);
getModel.setJcoClient(<your client>);

Do check that the structure of the BAPI/RFC has not changed.

Hi

You have to Create the Model from scratch using the new JCO destinations and do the model bindings and context mappings.NO WAY OUT. I know, this is tedious but this is the most safe way to accomplish this. Although in the SDN you will find articles that describes how to change JCO destinations after model creation but that doesn't work correctly.

Hope this helps
