• What is the cause and solution for SAP error message IP421 - Tolerances > 100% are not allowed ?

  The SAP error message IP421 "Tolerances > 100% are not allowed" typically occurs in the context of production planning or maintenance planning when you are trying to set tolerances for operations or activities that exceed the allowable limits. This error is often related to the configuration of tolerances in the system, particularly in the context of work orders, production orders, or maintenance orders.
  Cause:
  
  Tolerance Settings: The error is triggered when the system detects that the tolerance percentage you are trying to set for a particular operation or activity exceeds 100%. In SAP, tolerances are used to define acceptable limits for various parameters, such as time, costs, or quantities.
  Configuration Issues: The configuration settings in the system may not allow for tolerances greater than 100%, which is a standard practice to ensure that operations remain within reasonable limits.
  Data Entry Error: It could also be a simple data entry error where the user mistakenly inputs a value greater than 100%.
  
  Solution:
  
  Check Tolerance Values: Review the tolerance values you are trying to set. Ensure that they are within the acceptable range (0% to 100%).
  Adjust Configuration: If you need to allow for tolerances greater than 100% for specific business requirements, you may need to adjust the configuration settings in the SAP system. This typically requires access to the configuration settings in the SAP IMG (Implementation Guide).
  Correct Data Entry: If the error is due to incorrect data entry, correct the values to ensure they are within the allowed limits.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to set tolerances correctly in your specific context (e.g., production orders, maintenance orders).
  User Training: Ensure that users are trained on the correct procedures for entering tolerance values to prevent future occurrences of this error.
