  Solution:
  
  Check Parameter Lengths: Review the definition of the import parameters in the dialog program. Ensure that the data being passed does not exceed these lengths.
  Data Validation: Implement checks in the calling program to validate the length of the data before passing it to the dialog program. You can use the strlen() function or similar to check the length of the data.
  Trimming Data: If applicable, trim the data to fit within the defined limits before passing it to the dialog program.
  Review Changes: If there have been recent changes to the dialog program or the data structures, ensure that all calling programs are updated accordingly.
  Debugging: Use debugging tools to step through the code and identify the exact point where the overflow occurs. This can help in understanding the data being passed and its length.
