• What is the cause and solution for SAP error message 1G661 - Retroactive condition change not possible. New valid-from date: &1 ?

  The SAP error message 1G661 ("Retroactive condition change not possible. New valid-from date: &1") typically occurs in the context of pricing conditions in SAP, particularly when dealing with retroactive changes to pricing conditions in sales documents or purchasing documents.
  Cause:
  This error arises when you attempt to change a pricing condition that has already been applied to a document (like a sales order or purchase order) with a new valid-from date that is earlier than the date of the existing condition. SAP does not allow retroactive changes to conditions that have already been processed in documents, as this could lead to inconsistencies in pricing and accounting.
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Validity Dates: Review the validity dates of the pricing conditions you are trying to change. Ensure that the new valid-from date is not earlier than the date of the existing condition in the document.
  
  
  Adjust the Valid-From Date: If you need to change the condition, you may need to adjust the valid-from date to a date that is equal to or later than the existing condition's date.
  
  
  Use Condition Records: If you need to apply a new condition retroactively, you may need to create a new condition record with a valid-from date that is appropriate for future transactions, rather than trying to change an existing one.
  
  
  Check Document Status: Ensure that the document (sales order, purchase order, etc.) is in a status that allows for changes. If the document is already processed (e.g., delivered, invoiced), you may need to reverse or adjust the document first.
  
  
  Consult with a Functional Consultant: If you are unsure about the implications of changing pricing conditions or if the issue persists, consult with an SAP functional consultant who specializes in pricing and conditions.
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like VK11 (Create Condition) or VK12 (Change Condition) to manage pricing conditions.
  Condition Types: Understand the specific condition type you are working with, as different condition types may have different rules regarding retroactive changes.
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or updates related to this error message.
  Documentation: Review SAP documentation on pricing conditions and retroactive changes for more detailed information on how to manage these scenarios.
  
  By following these steps, you should be able to address the error and manage your pricing conditions effectively.
