Issue details explained with example and calculation

What is a Rounding difference (field KDIFF)

Difference in group condition value , occurs when calculation of header and item level values , for the same group.

Only applicable for condition type where ‘RoundDiffComp’ checkbox is activated and without the use of the group key routine.

Example

At Header Level 20% Discount for a group condition

At Item level

Now the different in total value from header (1.51) to item (1.52) = 0.01-

If there is a difference this difference (the so-called rounding difference (field KDIFF)) is added to one of the item condition values so the total of the item condition values corresponds to the condition value calculated on document level .
The system displays the rounding difference in the affected condition detail.

Distribution of Rounding difference (field KDIFF)

• Rounding difference is added to the item whose condition has the absolute largest condition value (technically KWERT) in this group (as per example, in line item 20 , so as to ensure no difference between header and item level calculation)

• If Condition values of a group are equally, the rounding difference adjustment is assigned to the last item in the group

• If all condition values are equal to zero, the rounding difference adjustment is now added to the item of a group that has the absolute largest condition basis (technically KAWRT).

What is Condition type DIFF?

Total value of the document to be rounded.

Example: the total value must be divisible by 0.05

System adjust the net value to ensure the TAX is not affected, thus condition type DIFF value is added with net value = 151+ (0.03-) = 150.93

Net value (inclusive of Diff condition type) = 150.93 and tax 4.53, Total = 155.30

Example for DIFF = group condition
