KONV-KKURS exchange rate overwrite

[Yesh]

Hi Team , 

Will there be any impact if we write a custom logic in the user exit to overwrite KONV-KKURS rate with condition to document currency conversion during billing document creation ?

Hi Yesh,
If you implement custom logic in a user exit to overwrite KONV-KKURS with your own conversion rate the Pricing Consistency, Condition values may no longer match the original order or delivery pricing. This can lead to discrepancies between FI postings and SD documents.

Accounting Integration
The exchange rate is critical for revenue postings to FI/CO. Overwriting it may cause mismatches between SD billing and FI accounting documents.

Tax Calculations
If taxes are condition-based, changing the rate can alter tax amounts unexpectedly.

Reconciliation Issues
Reports comparing SD and FI (e.g., CO-PA, revenue recognition) may show differences if exchange rates are inconsistent.

Audit/Compliance
Exchange rates are often subject to audit requirements. Custom overrides could raise compliance concerns if not properly documented.

My advice to your, instead of directly overwriting KONV-KKURS. Use standard exchange rate determination (OB08, currency type settings). If business requires a special rate (e.g., fixed contract rate), consider. Creating a custom condition type for exchange rate handling. Using pricing routines (VOFM) rather than hard overwriting KONV fields. Storing the custom rate in a Z-field for reporting, while keeping KONV consistent.

Hi Mohammed Baser , Thanks for your response. My scenario is order-related billing and this is for reporting requirement to store the exchange rate which is determined in billing document.As KONV-KKURS holds the rate of condition to local currency in certain cases and condition to document currency in certain cases but during billing document creation for baseprice condition type the exchange rate calculation will be always condition to document currency combination.
