Exception Structure Field not Found

[Former Member]

Hi all!

I'm having a strange trouble with a webdynpro app.

I have a BAPI with a structure as an Input parameter, and another structure as an Output parameter, as well as the Return table.

I imported the model to my app, created the custom controller, added the fields to the view, everything seems all right, but when I deploy and run the app, I get the exception that the field Versn of the Output structure is not found:

com.sap.tc.webdynpro.progmodel.context.ContextConfigurationException: DataNodeInfo(Main.Zbapi_Wty_Codigo_Averia_Input.Output.Wa_Averia_Output): structure field Versn not found

at com.sap.tc.webdynpro.progmodel.context.DataAttributeInfo.init(DataAttributeInfo.java(Compiled Code))

at com.sap.tc.webdynpro.progmodel.context.NodeInfo.init(NodeInfo.java(Compiled Code))

at com.sap.tc.webdynpro.progmodel.context.NodeInfo.init(NodeInfo.java(Compiled Code))

This is the first time it happens, I've used other BAPIs with a similar structure, but I got no errors, so I don't understand what might be wrong this time.

Has any of you have a problem like this??

Thanx.

Hi Sukant!

thank you for your response, but I already rebuild and redeploy teh app. I even created a new proyect for that BAPI only, and I'm still getting the same error.

Thanx

Are you sure this BAPI is not imported by any body else previously?

Because J2EE engine caches the meta data of the RFC, if it was imported previously and after that if RFC structure is modified you will see this kind of problems. You restart your J2EE engine and try again. That should solve your problem.

Thanks a lot Abhilash!

Restarting the J2EE server solved my problem.

Now, I was wondering, why does this happen?? is there a way to prevent it? because I don't wanna have to restar the server everytime I modify a BAPI...

Does anyone have any info about it??

Thanx

Jesus

Which version you are using?

From NW04 or 6.40 SP20 and NW04S or 7.0 SP10 onwards a new concept introduced called <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/10465350-b4f5-2910-61ba-a58282b3b6df">Metadata Cache Invalidation for Adaptive RFC Models</a>
