SAP Error Message - Details

• Message type: E = Error

• Message class: DT - Table activation (incl. indexes)

• Message number: 467

• Message text: Introduction of field & will invalidate the data of subsequent INT2 field

What causes this issue?

You have introduced a Decfloat scale field in front of an existing INT2
field. In this case, the INT2 field would be used for management data on
the database - which was possibly not the original intention for this
field.

System Response

The table is activated with a warning.

How to fix this error?

It is possible to introduce a new INT2 field after the Decfloat scale
field if the already existing INT2 field had a different purpose.

• What is the cause and solution for SAP error message DT467 - Introduction of field & will invalidate the data of subsequent INT2 field ?

  The SAP error message DT467, which states "Introduction of field & will invalidate the data of subsequent INT2 field," typically occurs during the data dictionary changes or when modifying the structure of a table or a data element in the ABAP Dictionary. This error indicates that the introduction of a new field (denoted by &) will affect the integrity of existing data, particularly for fields that are defined as INT2 (integer type with a 2-byte length).
  Cause:
  
  Data Structure Change: The error arises when a new field is added to a table or structure that has an existing INT2 field. The addition of the new field may change the way data is stored or interpreted, leading to potential data inconsistencies.
  Field Length and Data Type: The introduction of a new field may exceed the defined length of the structure or may conflict with the data type of existing fields, particularly if the new field is expected to take up space that the INT2 field relies on.
  
  Solution:
  
  Review Data Structure: Analyze the data structure of the table or structure where the error is occurring. Ensure that the addition of the new field does not conflict with existing fields.
  Adjust Field Definitions: If necessary, modify the definitions of the existing fields or the new field to ensure compatibility. This may involve changing the data type or length of the fields.
  Data Migration: If the new field is essential and cannot be adjusted, consider implementing a data migration strategy to handle existing data. This may involve creating a new table or structure that accommodates the new field without affecting the INT2 field.
  Testing: After making changes, thoroughly test the data structure to ensure that the integrity of the data is maintained and that the error does not reoccur.
  
  Related Information:
  
  Data Dictionary (SE11): Use transaction SE11 to view and modify the data dictionary objects. This is where you can check the structure of the table or data element causing the issue.
  ABAP Development: If you are a developer, ensure that you follow best practices for modifying data structures, including proper versioning and documentation.
  SAP Notes: Check SAP Notes for any specific guidance or patches related to this error message, as there may be known issues or updates that address similar problems.
  
  Conclusion:
  The DT467 error is a warning about potential data integrity issues when modifying data structures in SAP. By carefully reviewing and adjusting the data definitions, you can resolve the issue and maintain the integrity of your data. Always ensure to back up your data and test changes in a development environment before applying them to production.
