Hello.

try to remove already imported ARFC2 model which you want to reimport and import it again, but you should be careful with context nodes names. It may change and then you need to rename it as it was before or to fix your java source code.

In my experience the way has worked

Good luck

hi Anton Shypkov,

your solution works , but in case the Already imported ARFC2 model has more rfcs like 10 to 15 and now i have another one 16th rfc that i need to import in that case  how to over come with out disturbing the existing ones ... it will be help full if we dont delete the existing one ...

Hi govardan raj,

U have tow option to resolve this issue.

1. Restart portal server

2. Or else u can invalidate your jco models that used for that particular RFC .

Please check . i think this will sure work.

Thanks and regards,

Hi Meghal shah

Restarting portal server and invalidation of Jcos didnt work , as it was working usually in NWDS 7.0.14 ... im using the portal 7.3 and netweaver 7.3

Hi,

  After re import please do

Invalidate the cache or restart the J2ee engine server.

Note: Please check you have mapped corresponding RFC structure to the context attribute.
