• What is the cause and solution for SAP error message FKKINV335 - You are changing the rules for individual charges/discounts in the past ?

  The SAP error message FKKINV335 indicates that you are attempting to change the rules for individual charges or discounts in the past, which is not allowed in the system. This error typically arises in the context of billing or invoicing processes within the SAP Convergent Charging or Contract Accounts Receivable and Payable (FI-CA) modules.
  Cause:
  
  Historical Data Integrity: SAP maintains the integrity of historical data. Changing rules for charges or discounts that have already been applied to past transactions can lead to inconsistencies and inaccuracies in financial reporting.
  Configuration Changes: If you are trying to modify the configuration settings for charges or discounts that have already been processed, the system will prevent this to ensure that past transactions remain unchanged.
  
  Solution:
  
  Review Changes: Ensure that you are not trying to apply changes to historical data. If you need to change rules, do so for future transactions only.
  Create New Rules: If you need to implement new rules, consider creating new charge/discount rules that will apply to future transactions rather than modifying existing ones.
  Consult Documentation: Refer to SAP documentation or your organization's SAP guidelines to understand the proper procedures for managing charges and discounts.
  Use Adjustment Transactions: If you need to correct or adjust past transactions, consider using adjustment transactions or credit memos instead of changing the original rules.
  Contact Support: If you believe the change is necessary and should be allowed, consult with your SAP support team or a functional consultant to explore possible workarounds or solutions.
