Replace the gross price with a promotional price with posting the differenc

Question

Hi,
I need to create a new discount condition type that will replace the gross price with a promotional price. The difference between the gross price and promotional price must be posted in a discount G/L account.
Example :
Gross price : 100,99$
If the customer buy more than 10 of this material (qty >10) then the price should be 89,99$ and the 11$ difference should be posted in a discount G/L account.
I've searched in the forum and found no information on that. I've tried to look at all the standard SAP condition types to see if one is matching my needs but didn't find.
I've also searched in the OSS.
Replacing the gross price with a promotional price is no big deal but posting the difference in a separate discount G/L account : i don't know how to do it.
Could you help me, please ?
Thanks in advance.

Answer 1

This can be controlled by maintaining scales for Discount for material based on quantity. This can be maintained in Scale (Step type symbol) in T.Code VK11 / VK12 for Discount Condition.
Condition Types:
  The condition type determines the category of a condition and how it is used.
  The calculation type and the scale base type can be controlled for each condition type.
For Example: Scale for Condition Type PROO
1   pieces  800  uni
10  pieces  750  uni
100  pieces  700  uni
  Possible scale base types - Possible calculation types
Value - Percentage from an initial value Fixed amount
Quantity - Amount per unit of measure
Weight - Amount per unit of weight
Volumes - Amount per unit of volume
Time period - Quantity per unit of time
  Each condition type can be set as an automatic surcharge, discount or either.
  Condition Type in Pricing Procedure can be set as Manual, Mandatory or Statistical, as per requirement..
  Condition types: A calculation or formula used for a component of pricing.
