  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Input Values: Review the data you are trying to enter in the field. Ensure that you are using only non-numerical characters. If the field is meant for text, avoid using any numbers.
  
  
  Field Configuration: If you have access to the configuration settings, check the field definitions in the relevant transaction or module. Ensure that the field is correctly set up to accept the intended data type.
