How To Fix TB414 - Only compare is possible as selection is in non-key fields

SAP Error Message - Details

• Message type: E = Error

• Message class: TB - SM31 table maintenance messages

• Message number: 414

• Message text: Only compare is possible as selection is in non-key fields

What causes this issue?

A table view in which selection conditions for non-key fields are
formulated cannot be adjusted.
Selection conditions can be formulated when the table view is defined
(static conditions). Alternatively, you can work with a restricted data
area (dynamic conditions) when maintaining table views.

System Response

The table view can be compared.

How to fix this error?

If you have only formulated dynamic conditions for non-key fields, you
need to cancel these by exiting from <LS>Compare</> and working in the
table maintenance function either with all data or else just
formulating restrictions for key fields.

• What is the cause and solution for SAP error message TB414 - Only compare is possible as selection is in non-key fields ?

  The SAP error message TB414 ("Only compare is possible as selection is in non-key fields") typically occurs when you are trying to perform a selection or comparison operation in a query or report that involves non-key fields. This error indicates that the operation you are attempting is not valid because the fields involved in the selection criteria are not part of the key fields of the database table.
  Cause:
  
  Non-Key Fields: The fields you are trying to use in your selection criteria are not defined as key fields in the underlying database table. In SAP, key fields are used to uniquely identify records, while non-key fields do not have this property.
  Query or Report Design: The way the query or report is designed may be attempting to filter or compare data based on non-key fields, which is not allowed in certain contexts.
  
  Solution:
  
  Review Selection Criteria: Check the selection criteria you are using in your query or report. Ensure that you are using key fields for any operations that require unique identification of records.
  Modify Query/Report: If you need to filter or compare based on non-key fields, consider modifying the query or report to use key fields instead. Alternatively, you may need to adjust the logic to accommodate the limitations of non-key fields.
  Use Appropriate Functions: If you need to perform operations on non-key fields, consider using functions or methods that are designed to handle such cases, such as aggregating data or using joins that include key fields.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to properly structure your queries and reports, especially when dealing with non-key fields.
  
  Related Information:
  
  Key Fields vs. Non-Key Fields: Understanding the difference between key and non-key fields is crucial in SAP. Key fields are indexed and can be used for efficient data retrieval, while non-key fields may not have the same performance characteristics.
  Database Table Structure: Familiarize yourself with the structure of the database tables you are working with, including which fields are defined as key fields.
  SAP Query Tools: If you are using SAP Query or similar tools, ensure that you are aware of the limitations and capabilities of these tools regarding field selection and comparison.
