Invoice unmatched cost line auto approval

Hi All,

We are on  6.3.1 version.

Need clarification on a scenario, I have header level/line level tolerance rule setup.

When we receive  original invoice which has an additional accessorial which is not available on the shipment, auto approval on invoice is not working.

e.g. Shipment cost BASE 4.38                              Invoice Base           4.38

                             FSC 1                                    FSC                        1     

                                                                           ISC                          0.01

My line level tolerance setup were 1% accessorial initially. It means line level tolerance for Base and accessorial : Values in allowable percentage Below = 100%, Allowable percentage above = 1%.

I hoped that above is not working since, OTM tries looking up as a percentage of Shipment Cost and is not able to find any related shipment cost.
