• The SAP error message /PLMI/BO_RCA_OPT021: Sum of lower limits of optimization items is greater than 100% typically occurs in the context of optimization problems, particularly when using the SAP Advanced Planning and Optimization (APO) module or similar planning tools. This error indicates that the sum of the lower limits set for various optimization items exceeds 100%, which is not permissible.
  
  Cause:
  
  Configuration Error: The lower limits for the optimization items (e.g., production, inventory, etc.) have been set incorrectly, leading to a total that exceeds 100%.
  Data Entry Mistake: During the setup of the optimization parameters, incorrect values may have been entered for the lower limits.
  Modeling Issues: The optimization model may not be correctly defined, leading to conflicting constraints.
  
  
  Solution:
  
  Review Lower Limits: Check the lower limits set for each optimization item in the configuration. Ensure that the sum of these limits does not exceed 100%.
  Adjust Values: If the sum exceeds 100%, adjust the lower limits
