  Data Type Mismatch: The data type defined for the field in the database or application layer may not support decimal values.
  
  Solution:
  
  Check Input Values: Ensure that the values you are entering do not contain any decimal places. Round off any decimal values to the nearest whole number.
  Field Settings: If you have access to configuration settings, check the field settings in the relevant transaction or module to confirm that it is set to accept only integer values.
  Data Validation: Implement data validation checks in your input forms or processes to prevent users from entering decimal values in fields that do not support them.
  Consult Documentation: Review the SAP documentation or help files related to the specific transaction or module to understand the expected input formats.
