Issue with Scale base routines in Pricing

Question

Hi All,
                This is regarding one issue I am facing in Invoice creation.
It happens randomly in some invoices (impact is in <5 % of invoices) that a discount condition value is incorrectly calculated when created through batch job.
This issue is not replicable in any of the lower environments.
When we cancel the invoice in produciton system and recreate it, the values are calculated correctly and we failed to replicate it even in production to find the root cause.
Here are the details:
We have a custom condition type which is a group condition (header as well as item) which is set in percentage where customer is supposed to get a discount (for eg. 1 % on the net price)
We have a Scale Base value routine which fetches the ‘scale base value’ from a custom table and assigns it to the item on the invoice (XKOMV-KSTBS).
All further calculation happens in standard SAP code where it checks the scales maintained in the condition record and applies the correct rate so the discount is applied accordingly.
Our pricing routine is working fine and is passing correct value to the scale base field.
The issue is in standard SAP code which applies the discount.
For all the impacted invoices, we have correct scale base values (fetched in our routine) but the corresponding discounts (KONV-KBETR and KONV-KWERT) are zero.
Only the last item in all the invoices shows a large negative value which is wrong .
Please guide me in finding the root cause.

Hi,
These requirements should be met to fetch the condition record in the document.
1 = Different Payer
If this requirement is assigned to the condition type, the sold-to-party and payer should be different, so it will be picked up in the document.
2 = Item with Pricing
The item category of the item should be relevent for pricing.
3 = Foreign currency doc
The company code currency is derived from sales org in a sales document. But we can change the document currency in the sales document header also. And condition also can be maintianed in different currency. If this requirement is assigned, the company code currency and document currency should be different.
4 = Cost
If this requirement is set, the item should be relevent for cost determination (setting in item category)
5 = No Condit Exclusion
If this requirement is set, it will not consider the condition, if any condition exclusion is maintianed for it.
