  The SAP error message KX126, which indicates a "Program error when reading an internal table," typically arises when there is an issue with the internal table being accessed in the ABAP program. This can occur due to various reasons, such as:
  Causes:
  
  Uninitialized Internal Table: The internal table may not have been properly initialized or filled with data before it is accessed.
  Index Out of Bounds: The program may be trying to access an index of the internal table that does not exist (e.g., accessing an index greater than the number of entries in the table).
  Data Type Mismatch: There may be a mismatch between the expected data type of the internal table and the actual data being processed.
  Corrupted Data: The internal table may contain corrupted or unexpected data, leading to runtime errors.

  Solutions:
  
  Check Initialization: Ensure that the internal table is properly initialized and populated with data before it is accessed.

  Data Type Consistency: Verify that the data types used in the internal table declaration match the data being processed.
  Debugging: Use the ABAP debugger to step through the code and inspect the contents of the internal table at runtime. This can help identify where the error occurs.
  Error Handling: Implement error handling to gracefully manage situations where the internal table may not contain the expected data.
