Creating two different Invoice numbers when CN-China Localization is ON

 Hi,I am working on an issue related to CN localization where it created two invoice numbers for main line(Line type used CS) & freight line(Line Type used CF) on same sales order.

I had a check on following:-

1.Sold to,Payment terms,Currency is same.

2. Invoice consolidation is Off in customer billing information.

3. Schedule Invoice date in F49211 is same for both the lines.

If CN localization is off it works fine by creating a single Invoice number for both the lines.

Steps used:-

1. sales order created.

2. Shipment/Load approved,Confirmed.

3. Ran Freight update,at this stage Freight line got added to sales detail line.
