How To Fix VVSCSIM035 - Result of simulation run probably differs from update run

SAP Error Message - Details

• Message type: E = Error

• Message class: VVSCSIM - Simulation of Payment Plans (New)

• Message number: 035

• Message text: Result of simulation run probably differs from update run

What causes this issue?

As the system does not write the reversal information to the database in
simulation mode, the forward simulation is processed for an old dataset.
This could lead to discrepancies between the update run and the
simulation run.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message VVSCSIM035 - Result of simulation run probably differs from update run ?

  The SAP error message VVSCSIM035 indicates that the results of a simulation run may differ from those of an actual update run. This message typically arises in the context of the SAP Sales and Distribution (SD) module, particularly when simulating sales order processing, billing, or other related transactions.
  Cause:
  The error can occur due to several reasons, including:
  
  Data Inconsistencies: The data used in the simulation run may not match the data in the database, leading to discrepancies in results.
  Configuration Issues: Certain configurations in the system may lead to different processing logic between simulation and actual update runs.
  Custom Code: If there are custom enhancements or user exits that affect the processing logic, they may behave differently in simulation mode compared to the actual update.
  Missing Authorizations: Sometimes, the user executing the simulation may not have the same authorizations as when executing the actual transaction, leading to different results.
  Transaction Variants: Different transaction variants or settings may be applied during simulation versus the actual execution.
  
  Solution:
  To resolve the issue, consider the following steps:
  
  Check Data Consistency: Ensure that the data being used in the simulation is consistent with the data in the database. Verify that all necessary master data and transactional data are correctly maintained.
  Review Configuration: Check the configuration settings in the SAP system related to the transaction you are simulating. Ensure that they are set up correctly and consistently.
  Analyze Custom Code: If there are any custom enhancements or user exits, review the code to ensure that it behaves the same way in both simulation and update modes.
  User Authorizations: Verify that the user executing the simulation has the necessary authorizations to perform the transaction. If there are restrictions, they may lead to different results.
  Test in a Different Environment: If possible, try running the simulation in a different environment (e.g., development or quality assurance) to see if the issue persists.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error message or provide additional guidance.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with the transaction codes related to the specific process you are working on (e.g., VA01 for sales order creation, VF01 for billing).
  SAP Documentation: Review the official SAP documentation for the Sales and Distribution module to understand the expected behavior of simulation versus update runs.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  
  By following these steps, you should be able to identify the cause of the VVSCSIM035 error and implement a suitable solution.
