Hi,

If it is RFC,ARFC,WS,AWS you cann't edit via Model CLass editor in NWDS. These model are imported as immutable model in NWDS

You have to change at backend and then reimport the model.

Hi

I got an exception while importing the model:

plugin name = Web Dynpro Model Editor Services

plugin id = com.sap.ide.webdynpro.service.modeleditor

class = com.sap.ide.webdynpro.modeleditor.wizards.model.creation.ModelDialog

method = nextPressed

exception = org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.NullPointerException)

Any idea, what went wrong ?

You can check structures created now.

Go to Data Dictionary and navigate to simple type ans structures. CHeck if new structures have arrived.

Just deploy the same application and restart the server to make sure that there is no old data in the cache.

Hi,

I don't know on which Service pack you are working, but for me it is not possible to change

model structures and only be reimporting you can add fields that are also available in the backend system.

he Only thing you can do is creating a value node that is excactly the same as you model structure. Unfortuently, you can't use structurebinding because it follows the same rules.

Hi,

Can you plese let me know how to reimport the structure ( as the backend table I have changed, and want this to affect on the model class as well ) ?

Regards,

[former_member186016]

Hi,

You have to click on model and select reimport.

Select the entities you want to re-import now.

If same entities are selected (which are changed at backend) the new structures will be created in NWDS.

Hi,

You can right-click on the model name and select "<i>Reimport Model</i>".
