Recoveries at the Tax Level and Tax Rate Level

Hello,

Just wondering if anyone else out there is having problems when using different recoveries.  We setup a CA HST Standard recovery for federal and provincial at the tax level, we also have defaults set at the tax rate level because of BC and NS having different recovery rates then the standard.  However when you set a default at the tax rate level, invoices do not validate and there is a recovery error.  Oracle support and development stated that you need to remove defaults at the tax rate level and leave them at the tax level.  My assumption would be that the product should work with defaults
