Solution

 There could be more then one causes of the above problem.

1. User and responsibility in JCA file is not properly defined.

<jca:binding />
<operation name="APPS_AP_VENDOR_SITES_PKG_INSERT_NEW">
<jca:operation
IRepInternalName="PLSQL:AP_VENDOR_SITES_PKG:INSERT_ROW"
SchemaName="SYS_USER"
PackageName="AP_VENDOR_SITES_PKG"
ProcedureName="INSERT_ROW"
InteractionSpec="oracle.tip.adapter.apps.AppsStoredProcedureInteractionSpec"
Username="sysadmin"
Responsibility="System Administrator" >
</jca:operation>

 
2. User mentioned in JCA properties do not have access\correct responsibility assigned in OEBS setup

Following properties should be correctly mentioned in JCA file as well as in OEBS setup.

Username="sysadmin"
Responsibility="System Administrator" 


3. User in jdbc datasource doesn't have enough rights to execute the API.

In my case problem was with the datasource user which was configured in WLS console doen't had enough rights. I provide with super user or apps user to access or execute the Apps Adapter from SOA plateform and my problem was resolved.

I hope this solution helps.
