In this blog post you will get to know about Issues related Rounding in Pricing and group condition rounding issues.

Usually in sales process many customers faces the issues for rounding, how system calculates and perform the rounding in various cases, it is observed that below are the common issues faced by many customers

Ø Billing document condition value is updated wrong, rounding issue

Ø Rounding difference is updated in one of the line item

Ø Rounding difference is updated only in last line item, even though same values are there in all the line item etc.

Ø Group condition type calculation process

Ø Issues in Tax value calculation

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

Header	Total QTY	Percentage 20%	Item Value
	7.57	1.514	1.51

At Item level

Item	Line item	QTY	Percentage 20%	Item Value
	10	2.19	0.438	0.44
	20	5.38	1.076	1.08
Total				1.52

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)

Item	Line item	QTY	Percentage 20%	KDIFF	Item Value
	10	2.19	0.438		0.44
	20	5.38	1.076	0.01-	1.07
Total					1.51

• 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

Item	Total QTY	Rate	Item Value
	1	151	151	Net Value = 151
Tax		3%	4.53	Tax= 4.53
Total Value			155.53	Total Value = 151+ 4.53 = 155.53
Diff			0.03	Rounding till 0.05 = 155.50, thus Diff = 0.03

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

Item	Total QTY	Rate	Item Value
	1	151	150.97	151- 0.03 = 150.93
Tax		3%	4.53	Tax= 4.53, Same
Total Value			155.50	Total Value = 150.93+ 4.53 = 155.50
Diff			0.03

Example for DIFF = group condition

Item	Total QTY	Rate	Item Value	TAX 3%	Total Value
	1	151	151	4.53	155.53
	1	143	143	4.29	147.29
Total			294.00	8.82	302.82
Diff					0.02-
