How To Fix AUR018 - Mass simulation documents with identical billing periods exist

SAP Error Message - Details

• Message type: E = Error

• Message class: AUR - Unbilled Revenue Reporting and Mass Simulation

• Message number: 018

• Message text: Mass simulation documents with identical billing periods exist

What causes this issue?

You tried to reverse billing of mass simulation index &v1& for
installation &v2&. The two simulation documents &v3& and &v4& were
found for this index. These simulation documents have the same billing
period.
Possible cause of the problem:
You billed the mass simulation index
You then deleted the mass simulation index without deleting the
simulation document
You generated the mass simulation index again with identification &v1&
and billed it again.
You cannot reverse the billing of the mass simulation index.

• What is the cause and solution for SAP error message AUR018 - Mass simulation documents with identical billing periods exist ?

  The SAP error message AUR018, which states "Mass simulation documents with identical billing periods exist," typically occurs in the context of mass simulations in the SAP system, particularly when dealing with billing or invoicing processes. This error indicates that there are multiple simulation documents that share the same billing period, which can lead to conflicts or inconsistencies in the data processing.
  Cause:
  
  Duplicate Simulation Documents: The primary cause of this error is the existence of multiple mass simulation documents that have the same billing period. This can happen if simulations are run multiple times for the same period without clearing previous entries.
  Configuration Issues: There may be configuration settings in the billing or invoicing module that allow for overlapping billing periods, leading to this error.
  Data Integrity Issues: There could be issues with data integrity, such as incomplete or incorrect entries in the database that lead to the creation of duplicate simulation documents.
  
  Solution:
  
  Identify Duplicate Documents: Use transaction codes like SE16 or SE11 to access the relevant database tables (e.g., VBRK for billing documents) and identify any duplicate simulation documents for the same billing period.
  Delete or Archive Duplicates: Once identified, you can either delete or archive the duplicate simulation documents to resolve the conflict. Ensure that you have the necessary authorizations and that you follow your organization's data management policies.
  Adjust Simulation Parameters: When running mass simulations, ensure that the parameters (such as billing period) are set correctly to avoid overlaps. Consider implementing checks to prevent running simulations for the same period multiple times.
  Consult Documentation: Review SAP documentation or notes related to the AUR018 error for any specific recommendations or patches that may address this issue.
  Contact SAP Support: If the issue persists or if you are unsure about how to proceed, consider reaching out to SAP support for assistance. They may provide insights based on the specific configuration and version of your SAP system.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as VF04 (for billing document processing) and VF01 (for creating billing documents) to manage billing processes effectively.
  SAP Notes: Check for any SAP Notes related to AUR018 for updates or fixes that may be applicable to your version of SAP.
  User Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, providing additional insights or solutions.
  
  By following these steps, you should be able to resolve the AUR018 error and prevent it from occurring in the future.
