  The SAP error message OIUCA400, which states "Range From must be unique," typically occurs in the context of configuration or data entry within the SAP system, particularly in the Oil and Gas industry module (OIU). This error indicates that there is a conflict in the data ranges being defined, where the "From" value in a range is not unique, leading to ambiguity in the system.
  Cause:

  Configuration Issues: In some cases, the error may arise from incorrect configuration settings in the system.
  
  Solution:
  
  Check Existing Ranges: Review the existing range definitions in the relevant configuration area. Look for any duplicate "From" values and ensure that each range is unique.
  Modify Ranges: If duplicates are found, modify the ranges to ensure that each "From" value is unique. This may involve changing the values or adjusting the ranges to eliminate overlaps.
  Data Validation: Implement data validation checks to prevent users from entering duplicate ranges in the future.
  Consult Documentation: Refer to SAP documentation or help resources specific to the Oil and Gas module for guidance on setting up ranges correctly.
  Testing: After making changes, test the configuration to ensure that the error no longer occurs and that the system behaves as expected.
