How To Fix SABP_KEY_REDUNDANCY019 - &1 is more precise than &2

SAP Error Message - Details

• Message type: E = Error

• Message class: SABP_KEY_REDUNDANCY - Superfluous Keys Messages

• Message number: 019

• Message text: &1 is more precise than &2

What causes this issue?

The table key &V1& is unique and &V2& is not unique. However, the
components of &V1& are a subset of &V2&, which means that &V1& is more
selective than &V2&.
INCLUDE INCL_MIGRATION_SCENARIO
Check whether both keys are really needed or if one of the keys can be
removed.
The message is also issued if &V2& is a generic primary key whose
uniqueness is unknown. In this case, the worst case scenario is assumed
(that the primary key is not unique). However, since the unique
secondary key is a subset of the primary key at the same time, the
primary key must be unique. Check the definition of the primary key and
define it as unique if appropriate.

• What is the cause and solution for SAP error message SABP_KEY_REDUNDANCY019 - &1 is more precise than &2 ?

  The SAP error message SABP_KEY_REDUNDANCY019 indicates that there is a redundancy issue with the key fields in a data structure or table. Specifically, the message states that one key field is more precise than another, which means that the system has detected a conflict in the definitions of key fields that are supposed to uniquely identify records.
  Cause:
  This error typically arises in the following scenarios:
  
  Data Model Conflicts: When two or more key fields are defined in a way that one is more specific than the other, leading to ambiguity in data retrieval or processing.
  Inconsistent Key Definitions: If the key fields in a database table or structure are not aligned properly, it can lead to this error.
  Custom Development Issues: If there are custom programs or enhancements that manipulate key fields, they may inadvertently create conflicts.
  
  Solution:
  To resolve the SABP_KEY_REDUNDANCY019 error, you can follow these steps:
  
  
  Review Key Definitions: Check the definitions of the key fields in the relevant data structure or table. Ensure that they are defined consistently and that there are no overlaps in their precision.
  
  
  Adjust Key Fields: If you find that one key field is indeed more precise than another, consider adjusting the definitions. This may involve:
  
  Modifying the data model to ensure that key fields are unique and appropriately defined.
  Removing or altering redundant key fields that are causing the conflict.
  
  
  
  Check Custom Code: If the error is occurring in a custom program, review the code to ensure that it is not introducing redundancy in key field definitions.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific module or functionality you are working with. There may be specific guidelines or best practices for defining key fields.
  
  
  Testing: After making changes, thoroughly test the affected functionality to ensure that the error is resolved and that there are no unintended side effects.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
  Data Dictionary: Familiarize yourself with the Data Dictionary (SE11) in SAP, where you can view and modify table definitions and key fields.
  Debugging: If the error persists, consider using the debugging tools in SAP to trace the execution and identify where the redundancy is being introduced.
  
  By following these steps, you should be able to identify and resolve the cause of the SABP_KEY_REDUNDANCY019 error in your SAP system.
