• What is the cause and solution for SAP error message PLA643 - IT &1 : will not be simulated. Existing records in database will be used ?

  The SAP error message PLA643 indicates that a simulation for a particular process (often related to planning or logistics) cannot be performed because there are existing records in the database that will be used instead. This typically occurs in the context of planning runs, where the system is trying to simulate a planning scenario but finds that there are already existing data records that it will utilize.
  Cause:
  
  Existing Data: The primary cause of this error is the presence of existing records in the database that the system deems relevant for the operation you are trying to perform. This could be due to previous planning runs or data that has been manually entered.
  Configuration Settings: Certain configuration settings in the planning module may prevent simulation if there are existing records.
  Locking Mechanisms: If the data is locked by another process or user, the system may not allow a simulation to proceed.
  
  Solution:
  
  Check Existing Records: Review the existing records in the database that are causing the issue. You may need to delete or modify these records if they are not needed.
  Run Without Simulation: If the existing records are valid and you do not need to simulate, you can proceed with the operation without simulation.
  Adjust Configuration: If applicable, check the configuration settings in the planning module to see if there are options to allow simulation even when records exist.
  Clear Locks: Ensure that there are no locks on the data that might be preventing the simulation. You can check for locks using transaction codes like SM12.
  Consult Documentation: Refer to SAP documentation or help resources for specific details related to the planning module you are working with, as the error may have specific implications based on the context.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MD01 (MRP Run), MD02 (Single-item, Multi-level Planning), or others depending on your specific planning scenario.
