Tax calculation in Pricing Procedure

Question

Hi Guys,
I have a pricing procedure setup to be modified for calculation of surcharge. The current pricing procedure calculates surcharge based on total price. Needs to change it to calculate on Unit price.How to achieve this?
Current Setup
Price    Unit Price      Qty.    Net Price
PR00       655.55          5       3277.75
ZSUR = 3277.75*12/100 = 393.33
Required setup
Price    Unit Price  Qty.    Net Price
PR00       655.55          5       3275
ZSUR = 655*12/100 = 78.666 = 78.67
Then this should be multiplied with the qty. 78.67*5 = 393.35
How to achieve this.
Thanks

Answer 1

I solved this same issue by doing the following.
When determining ZSUR, create a Condition formula for alternative calculation type in VOFM.
calculate the 12% off of the PR00 each price and round this result to 2 decimals. In your example you would get .12 * 655.55 = 78.666 commercial rounded to 78.67, then multiply this rounded result with qty to get your extended amount 78.67 * 5 = 393.35 and put the result in XKWERT for ZSUR.
With this type of calcualtion you will always get consistant pricing regardless of qty. When you are finished with your formula assign it within config of the pricing procedure on your ZSUR
line. Hope this helps.
When calculating .12 * 655.55 , create a working data field and do a 'like' to netpr in your formula:
eg DATA: ZZEA LIKE KOMP-NETPR. ( netpr is curr dec 2)
when calculating zzea = .12 * 655.55 since the field is defined as 2 decimal, commercial rounding will be the default calculation(round up if >= .005, down if < .005). So in your example 78.666 = 78.67
Code looks like(had to deal with floating decimals):
DATA: ZZEA LIKE KOMP-NETPR.
ZZEA = KOMP-NETPR * XKOMV-KBETR / 100000.
XKWERT = ZZEA * KOMP-MGAME / 1000.
