  The SAP error message GTCN_MESSAGE272, which indicates that "Duplicate data exists in Excel; check your entry," typically arises when you are trying to upload or import data into SAP from an Excel file, and the system detects duplicate entries that violate the uniqueness constraints defined in the target database table.
  Cause:
  
  Duplicate Entries: The most common cause is that the Excel file you are trying to upload contains duplicate rows or values in fields that are expected to be unique (e.g., primary keys, unique identifiers).
  Data Validation Rules: The target SAP system may have specific validation rules that require certain fields to be unique, and duplicates in the Excel file violate these rules.

  Solution:
  
  
  Identify Duplicates:
  
  Open the Excel file and use Excel's built-in features to identify duplicates. You can use the "Conditional Formatting" feature to highlight duplicate values or use the "Remove Duplicates" feature to eliminate them.

  Remove or Correct Duplicates:

  Revalidate Data:
