• What is the cause and solution for SAP error message AJ650 - You changed billing-specific data before the last billing (&1) ?

  The SAP error message AJ650 indicates that there has been a change to billing-specific data in a sales document (like a sales order or contract) after the last billing has occurred. This error typically arises in the context of billing processes in SAP, particularly when using the SD (Sales and Distribution) module.
  Cause:
  The error occurs because SAP enforces data integrity and consistency in billing processes. When billing-specific data (such as pricing, conditions, or terms) is modified after the last billing document has been created, it can lead to inconsistencies in the billing history and financial reporting. Therefore, SAP prevents further processing until the issue is resolved.
  Solution:
  To resolve the AJ650 error, you can take the following steps:
  
  
  Check Last Billing Document: Identify the last billing document created for the sales order or contract. You can do this by checking the billing history in the sales document.
  
  
  Review Changes: Determine what specific billing-related data was changed after the last billing. This could include changes to pricing conditions, payment terms, or other relevant fields.
  
  
  Revert Changes: If possible, revert the changes made to the billing-specific data back to the state it was in before the last billing. This may involve undoing any updates or modifications.
  
  
  Create a New Billing Document: If the changes are necessary and cannot be reverted, you may need to create a new billing document. This can be done by:
  
  Canceling the last billing document (if applicable).
  Making the necessary changes to the sales document.
  Creating a new billing document.
  
  
  
  Consult Documentation: Refer to SAP documentation or your organization's internal guidelines for handling billing-specific data changes.
  
  
  Contact Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.

  SAP Notes: Check for any SAP Notes related to error AJ650 for additional insights or patches that may address the issue.
  User Authorizations: Ensure that you have the necessary authorizations to make changes to billing-specific data, as restrictions may also lead to errors.
