How To Fix SABP_KEY_REDUNDANCY010 - The components of &2 are a subset of &1

SAP Error Message - Details

• Message type: E = Error

• Message class: SABP_KEY_REDUNDANCY - Superfluous Keys Messages

• Message number: 010

• Message text: The components of &2 are a subset of &1

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 be removed.

• What is the cause and solution for SAP error message SABP_KEY_REDUNDANCY010 - The components of &2 are a subset of &1 ?

  The SAP error message SABP_KEY_REDUNDANCY010 indicates that there is a redundancy issue with the components of a particular object in the system. Specifically, it means that the components of the object identified by &2 are a subset of the components of another object identified by &1. This typically occurs in the context of Bill of Materials (BOM) or similar structures where components are defined.
  Cause:
  The error arises when:
  
  You are trying to create or modify a BOM or a similar structure, and the components you are trying to add or define are already included in another BOM or structure.
  The system detects that the components of the new BOM are not unique and are already part of an existing BOM, leading to redundancy.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing BOMs: Review the existing BOMs or structures in the system to see if the components you are trying to add already exist in another BOM. You can use transaction codes like CS03 (Display BOM) to check the details.
  
  
  Modify Components: If the components are indeed a subset of another BOM, you may need to either:
  
  Modify the new BOM to include different components that are not part of the existing BOM.
  If the intention is to create a new BOM with the same components, consider whether you need to create a new version of the existing BOM instead.
  
  
  
  Use Alternative Structures: If the components are meant to be shared across multiple BOMs, consider using alternative structures or configurations that allow for shared components without redundancy.
  
  
  Consult Documentation: Review SAP documentation or help resources for more specific guidance related to your version of SAP and the context in which you are working.
  
  
  Seek Help from SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support for assistance, especially if this is impacting critical business processes.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CS01 (Create BOM), CS02 (Change BOM), and CS03 (Display BOM).
  BOM Structure: Understand the structure of BOMs in your organization and how components are defined and related.
  SAP Notes: Check for any SAP Notes related to BOM management and redundancy issues, as they may provide additional insights or patches.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
