How To Fix SABP_KEY_REDUNDANCY022 - One key has the type SORTED, the other has the type HASHED

SAP Error Message - Details

• Message type: E = Error

• Message class: SABP_KEY_REDUNDANCY - Superfluous Keys Messages

• Message number: 022

• Message text: One key has the type SORTED, the other has the type HASHED

What causes this issue?

The unique table keys &V1& and &V2& have different types (SORTED and
HASHED). The components of &V2& are a subset of &V1&. Check whether both
keys are required.
INCLUDE INCL_MIGRATION_SCENARIO
If &V1& is a HASHED key, there is a genuine subset of its components
that is already unique. If &V1& is a SORTED key, there is a genuine
initial part that is already unique.
Remove the superfluous components from the key &V1&. The key is then
redundant to the key &V2&. Check whether only one of the two keys is
used or whether only one key is needed and therefore the other can be
removed.

• What is the cause and solution for SAP error message SABP_KEY_REDUNDANCY022 - One key has the type SORTED, the other has the type HASHED ?

  The SAP error message SABP_KEY_REDUNDANCY022 indicates that there is a redundancy issue with the keys defined in a database table or an internal table. Specifically, the error arises when one key is defined as a SORTED table and another key is defined as a HASHED table. This inconsistency can lead to confusion in how the data is accessed and manipulated.
  Cause:
  
  Key Type Mismatch: The error occurs because the same key field is being used in two different contexts where one is expected to be sorted (SORTED) and the other is expected to be hashed (HASHED). In ABAP, a sorted table allows for ordered access, while a hashed table allows for faster access based on a unique key.
  Table Definition: The issue often arises during the definition of internal tables or database tables where the key types are not aligned.
  
  Solution:
  To resolve this error, you need to ensure that the key types are consistent. Here are the steps you can take:
  
  
  Review Table Definitions: Check the definitions of the internal tables or database tables involved. Ensure that the key types are consistent across all definitions.
  
  If you are using a SORTED table, make sure that all keys are defined as sorted.
  If you are using a HASHED table, ensure that all keys are defined as hashed.
  
  
  
  Change Key Type: If you find that a key is incorrectly defined, change the key type to match the other key's type. For example, if you have a sorted table and you need to change it to a hashed table, modify the declaration accordingly.
  
  
  Code Review: Review the ABAP code where the tables are being used. Ensure that the operations performed on these tables are compatible with their key types.
  
  
  Testing: After making the necessary changes, test the program to ensure that the error is resolved and that the functionality is as expected.
  
  
  Related Information:
  
  SORTED Tables: These tables maintain the order of entries based on the key fields. They are useful when you need to access data in a specific order or perform range queries.
  HASHED Tables: These tables provide fast access to data based on unique keys. They are optimized for lookups and are not ordered.
  ABAP Documentation: Refer to the official SAP documentation for more details on internal table types and their usage.
  
  By ensuring that the key types are consistent and correctly defined, you can resolve the SABP_KEY_REDUNDANCY022 error and prevent it from occurring in the future.
