How To Fix SABP_KEY_REDUNDANCY007 - &1 is an initial part of &2

SAP Error Message - Details

• Message type: E = Error

• Message class: SABP_KEY_REDUNDANCY - Superfluous Keys Messages

• Message number: 007

• Message text: &1 is an initial part of &2

What causes this issue?

The table keys &V1& and &V2& are both of the type SORTED. The non-unique
key &V1& is an initial part of the unique key &V2&. Check whether both
keys are required.
INCLUDE INCL_MIGRATION_SCENARIO
The key &V2& has more components than &V1& and is thus more selective.
In the case of all statements where the key &V1& is used, &V2& could
also be used (exception: READ/DELETE # WITH TABLE KEY#, where all key
components have to be assigned exactly).
Check whether only one of the keys is used or could be used and whether
the other key can therefore be removed.

• What is the cause and solution for SAP error message SABP_KEY_REDUNDANCY007 - &1 is an initial part of &2 ?

  The SAP error message SABP_KEY_REDUNDANCY007 typically indicates a redundancy issue in the key fields of a data structure, such as a table or a data record. The message states that the first part of a key (denoted as &1) is an initial part of another key (denoted as &2). This usually occurs when there are overlapping or conflicting entries in a key field that should be unique.
  Cause:
  
  Key Redundancy: The error arises when there are two or more entries in a table or data structure where one key is a prefix of another. For example, if you have keys "123" and "1234", the first key is an initial part of the second key.
  Data Entry Issues: This can happen due to incorrect data entry or data migration processes where unique constraints are not properly enforced.
  Configuration Issues: In some cases, the configuration of the data model or the way the keys are defined may lead to this redundancy.
  
  Solution:
  
  Identify Redundant Entries: Check the entries in the relevant table or data structure to identify the conflicting keys. You can use SQL queries or transaction codes in SAP to list the entries.
  Modify or Remove Entries: Once you identify the redundant keys, you can either modify them to ensure uniqueness or remove the conflicting entries if they are not needed.
  Review Data Entry Processes: Ensure that data entry processes are designed to prevent such redundancies in the future. This may involve adding validation checks or constraints.
  Check Configuration: Review the configuration of the data model to ensure that key definitions are set up correctly and that they enforce uniqueness as required.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like SE11 (Data Dictionary), SE16 (Data Browser), or SE80 (Object Navigator) to investigate the data structure and entries.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP's support portal can provide additional insights.
  Documentation: Review the documentation for the specific module or application area where the error occurs to understand the expected behavior of key fields.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis or development team for further analysis and resolution.
