Difference in Rounded Tax amount for same Item and Unit Price

Hello,

We have the issue in the Tax calculation in the batch R42565.

The tax calculation is done on the line level.

We have executed the above batch for one of the Sales orders.

It contains total 7 Sales order lines among them 6 are exactly similar .

While debugging it is seen that for one of the lines among the above 6 , the rounded tax amount is having difference of 0.01.

For Example.

Suppose For the 6 lines the column values of table F42565 are as below

F42565.UPRC= 124.4556

F42565.ATXA, AEXP=124.46

The unrounded Tax amount , F42565.UATM = 7.4676 for all the 6 lines

But F42565.STAM= 7.47 for all the 6 lines except for LNID=3, where it is 7.46
