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

AUR018 - Overview

• 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.

AUR018 - Details

• 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
