Financial Tax Register doesnt shows correct details in R12

Hi ,

We are in 12.1.3 version .We are using Financial Tax Register (RXI).We obserbed the following descripencies.

• Incorrect Invoice Total.E.g If the Invoice has a line with USD100 and the line is charged with offset Tax.Then the FTR Gives as follows.

                               Line1  100  Tax 8

As offset              Line1 100  Tax -8

So the Total for Line1 becomes 200 0 which is incorrect.The offset lines should represent 0 as item and Tax as -8.

•      Incase Multiple Taxes on a single line.the first Tax calculation is showing correct but the rest Tax amount showing as zero.
• DFF Attributes gived in the RXI is not populating if we enter in the DFF .
