• What is the cause and solution for SAP error message FKKVT_ILLEGAL_STATE018 - Discount &1 is maintained so it overlaps &2 ?

  The SAP error message FKKVT_ILLEGAL_STATE018 indicates that there is a conflict with discount settings in the system. Specifically, it means that a discount (denoted as &1) is maintained in such a way that it overlaps with another discount or condition (denoted as &2). This typically occurs in the context of contract accounts or billing processes where multiple discounts or conditions are applied.
  Cause:
  
  
  Overlapping Discounts: The primary cause of this error is that two or more discounts are defined in a way that they cannot coexist for the same transaction or account. This can happen if:
  
  Discounts are defined for the same time period.
  Discounts are defined for the same conditions (e.g., customer group, product type).
  There are conflicting rules in the discount configuration.
  
  
  
  Configuration Issues: There may be issues in the configuration of discount settings in the SAP system, such as incorrect settings in the pricing procedure or discount conditions.
  
  
  Solution:
  
  
  Review Discount Conditions: Check the discount conditions that are defined in the system. Look for:
  
  Time periods: Ensure that the discounts do not overlap in terms of validity dates.
  Condition types: Verify that the condition types do not conflict with each other.
  
  
  
  Adjust Configuration: If necessary, adjust the configuration of the discounts:
  
  Modify the validity periods of the discounts to ensure they do not overlap.
  Change the conditions under which the discounts are applied to avoid conflicts.
  
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to configure discounts properly. This can provide insights into best practices and common pitfalls.
  
  
  Testing: After making changes, perform testing to ensure that the discounts are applied correctly without causing further errors.
  
  
  Seek Support: If the issue persists, consider reaching out to your SAP support team or consulting with an SAP expert who can provide more tailored assistance based on your specific configuration and business processes.

  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide updates related to discount handling in your version of SAP.
