I am trying to generate a service for the Oracle Applications Adapter (v2.0) against OA 11i (11.5.5) with wM6.0.1. When I attempt to generate the INVItem service I get the following error:

Can anyone point me in the direction of a fix?

Thanks

Its a known issue.
1-Open the Developer.
2-CLick on OracleApps Package.
3-Click on Pakcage Dependencies. Make OracleApps package dependent on WmRoot and version ..
4-Reload the Oracle Apps Package.
You will no longer get service generation problem.

Problem solved! Thanks
