VAT calculation issue on Bank payment fee (Sales Tax )

Dear All,

Need your help on below issue;

Running the below scenario on vendor payment with bank fee and vat required to calculate on bank fee, following financial entries required to generate;

Dr Entries 

Vendor Payment  100

Bank Fee              7

VAT/Sale tax       0.35

Cr Entries 

Bank  cr for Vendor  100

Bank cr for Bank fee    7

Bank cr for Vat         0.35

Same scenario works if we mark price include sales tax check box, but we need same for excluding sales tax 

Please consider that for Indian region we use sales tax word for VAT.
