This error indicates that there were issues during the simulation process, which could be due to various reasons.
  Possible Causes:
  
  Data Inconsistencies: There may be inconsistencies in the master data or transaction data, such as incorrect or missing information in the material master, production resources, or planning parameters.
  Configuration Issues: Incorrect configuration settings in the planning area, planning books, or key figures can lead to errors during simulation.
  Resource Constraints: If there are constraints on resources (e.g., capacity issues), the simulation may fail to find a feasible solution.
  Planning Version Issues: The planning version being used may not be correctly set up or may have been locked.
  User Authorizations: Lack of proper authorizations for the user executing the simulation can also lead to errors.
  Technical Issues: There may be underlying technical issues, such as system performance problems or bugs in the software.
  
  Solutions:
  
  Check Data Consistency: Review the master data and transaction data for any inconsistencies. Ensure that all necessary data is complete and accurate.
