last step of ".... web dynpro application accesing ABAP functions" FAILED

12 Views

Hello!!!

I can't run my app (Example: Creating a web dynpro application accessing ABAP functions).

I will be very grateful if someone tell me what is happening. While I'm developing I can connect to my was 6.20 to see de BAPI and other stuff, to use on my program, but once I deploy the app and try to test it... this is what it drops:

Error stacktrace:

I found at "How to Use the Web Dynpro Content Administrator.pdf" a good place to look for my mistake. But a big question appeared:

Once I get in the Web Dynpro Content Administrator and found my deplyed app I found this two JCo:

WD_MODELDATA_DEST

WD_RFC_METADATA_DEST

Witch status was a little grey diamond, or something like that. ¿Can somebody tell me what is happening with this Jco?

The page 27 of the pdf mentioned before, was different in my IDE SAP Developer Studio, the only option, by default, that give me was to choose between WD_MODELDATA_DEST and

WD_RFC_METADATA_DEST. I have two fields that must be fill to pass to the next dialog box or finished the creation RFC model.

Thanks a lot !!!
