Unable to reimport model.

[Former Member]

I'm using NWDS 7.2 SP03. I have to reimport several Adaptive RFC 2 Models. I successfully reimported some of them, but for some others I get a failure. In the Error Log there are these messages:

method: doReimportDynRfc2Model -> Adaptive RFC2 model reimport failed [Error: com.sap.cmi.modeltype.arfc2.wizard.ARFC2ModelCreationWizard Thread[ModalContext,6,main]]

Internal Error

Plug-In Name: Model Type Adaptive RFC 2

Internal Error : com.sap.cmi.modeltype.arfc2

Class : com.sap.cmi.modeltype.arfc2.wizard.ARFC2ModelCreationWizard$2

Method : doReimportDynRfc2Model

Message : Adaptive RFC2 model reimport failed

Exception : java.lang.NullPointerException: null

[Error: com.sap.ide.tools.services.ui.dialog.DialogService Thread[ModalContext,6,main]]

If I do a "Reimport preview" of the failing models I get a pop-up window with the message "Cannot find model delta"

and in the error log there is the message:

Internal Error

Plug-In Name: Model Type Adaptive RFC 2

Internal Error : com.sap.cmi.modeltype.arfc2

Class : com.sap.cmi.modeltype.arfc2.service.ARFC2ModelCreationService

Method : createModel()

Message : Failed to create model

Exception : java.lang.NullPointerException: null

[Error: com.sap.ide.tools.services.ui.dialog.DialogService Thread[main,6,main]]

Any help is greatly appreciated.

Looks NWDI issue. Try to install the latest SP if any available. If not try with some other older version.

Also try from some other computer and see.

Yugandhar,

thank you for your reply. I moved my workspace to another machine with a NWDS SP01 and it works!!

I got one question. At present my NWDS and the target NWCE are both at SP 03 level.

If I change the SP level of my NWDS, must I change also the NWCE?

In other words, the NWDS and NWCE can be at a different SP level?

Thank you and best regards,

Livio.

I am not sure about NWCE but i think it should be ok if its slightly different version.

Hi Livio,

You can use NWDS CE SP3 or lower, it will work properly.

For NWDS issue there in no need to change server NWCE.
