• What is the cause and solution for SAP error message EPS158 - Payment scheme &1 already contains contract account items ?

  The SAP error message EPS158, which states "Payment scheme &1 already contains contract account items," typically occurs in the context of contract account management within the SAP system. This error indicates that the payment scheme you are trying to assign or modify already has associated contract account items, which prevents further modifications or assignments.
  Cause:
  
  Existing Contract Account Items: The payment scheme you are trying to use is already linked to one or more contract account items. This can happen if you are trying to assign a payment scheme to a contract account that already has items associated with it.
  Data Integrity Rules: SAP enforces data integrity rules to ensure that payment schemes are not duplicated or incorrectly assigned, which can lead to inconsistencies in financial reporting and processing.
  
  Solution:
  
  Check Existing Assignments: Review the payment scheme and check which contract account items are already associated with it. You can do this by navigating to the relevant transaction in SAP (e.g., using transaction codes like FPL9 or FPAY) to view the details of the payment scheme.
  Remove Existing Items: If you need to change the payment scheme, you may need to remove the existing contract account items from the payment scheme before you can assign new ones. This can typically be done through the same transaction where you view the payment scheme.
  Create a New Payment Scheme: If the existing payment scheme is still needed for other contract accounts, consider creating a new payment scheme instead of modifying the existing one.
  Consult Documentation: Refer to SAP documentation or your organization's internal guidelines for managing payment schemes and contract accounts to ensure compliance with best practices.
