• What is the cause and solution for SAP error message DH171 - Literal &2 defined as default value for parameter &1 is incorrect ?

  The SAP error message DH171 indicates that there is an issue with a default value defined for a parameter in a data dictionary object, such as a table or a view. The message typically means that the literal value assigned as the default for a parameter is not valid or does not conform to the expected data type or format.
  Cause:
  
  Data Type Mismatch: The default value assigned to the parameter does not match the expected data type. For example, if the parameter is defined as an integer, but the default value is a string, this error will occur.
  Invalid Format: The default value may not be in the correct format. For instance, if a date is expected, but the default value is not in a recognized date format, it will trigger this error.
  Domain Constraints: If the parameter is associated with a domain that has specific value constraints, and the default value does not meet those constraints, the error will be raised.
  Missing Value: The default value might be missing or not properly defined in the data dictionary.
  
  Solution:
  
  Check Data Types: Verify that the default value for the parameter matches the expected data type. If the parameter is an integer, ensure the default value is an integer.
  Correct Format: Ensure that the default value is in the correct format. For example, if a date is required, make sure the default value is in the correct date format (e.g., YYYY-MM-DD).
  Review Domain: If the parameter is linked to a domain, check the domain definition to ensure that the default value complies with any constraints or allowed values.
  Update Default Value: If the default value is incorrect, update it in the data dictionary to a valid value that meets the requirements.
  Transport Requests: If changes are made in a development environment, ensure that they are transported to the appropriate environments (e.g., quality assurance, production) as needed.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like SE11 (Data Dictionary) to check and modify the definitions of tables, views, or domains.
  Documentation: Refer to SAP documentation for specific data types and domain constraints to ensure compliance.
  Testing: After making changes, test the functionality to ensure that the error is resolved and that the application behaves as expected.
  
  If the issue persists after checking these aspects, it may be beneficial to consult with a technical SAP consultant or refer to SAP support for further assistance.
