TDS functionality, India Localization

Hi All,

We have 3 invoices with 2 lines one with TDS tax codes in distribution and other with no tax code(Blank).

Threshold limit is 180000,CUMULATIVE and rate is 10%.There is no default TDS section code defined at additional information screen.

Invoice 1:-

Line1--100000--TDS tax code

Line2--90000--No tax code

Invoice 2:-

Line1--50000--TDS tax code

Line2--30000--No tax code

Invoice3:-

Line1--60000--TDS tax code

Line2--40000--No tax code

Here the amount where TDS code is present is 210000(100000+50000+60000), so our expected value for TDS was 10% of 210000=21000 but instead the TDS calculated was 6000.00 and 27000.00=33000(6000 on invoice3 which is ok but the remaining 27000 is calculated on the invoice amount of invoice1 and invoice2 i.e 190000+80000= 270000).
