Yes i only have this problem with the stored procedures i call, the entity fetches work fine.
This is the generated code for the stored prodecure which i call.
private static StoredProcedureCall CreateSysDtgetsysdateCall(IDataAccessCore dataAccessProvider, System.DateTime returnValue)
{
return new StoredProcedureCall(dataAccessProvider, "\"OLD_SCHEMA\".\"PA_SYS.DTGETSYSDATE\"", "SysDtgetsysdate")
.AddParameter("RETURN_VALUE", "Date", 0, ParameterDirection.ReturnValue, true, 0, 0, returnValue);
}
