Individual tax lines for each item in AP tax

Dear Community,

We want to implement AP tax for purchases using procurement module (43) and Accounts payable module (04). 

We have done the set ups as below.

1. Created a address book records for Tax authority.

2. Created Tax Area V5 for VAT 5% and the rate is 5%.

3. Created AAI PTV5;

And the tax explanation code is taken as 'V' as it is VAT recoverable.

Now we have created a purchase order for four items Aggregate 10mm, Aggregate 20mm, Aggregate 30mm, Aggregate 40mm. All come under same tax rate that is 5%.  We have given the tax explanation code 'V' and Tax area 'V5' for all the four items. We have done the receipt and voucher match also. After posting all the entries, when we check the voucher match entry the system has passed a summarised entry for VAT. We have even changed both the processing options in "4. Summarisation" for application P4314 to blank and checked but the result for VAT entry is same.
