• What is the cause and solution for SAP error message FKKBIX086 - Index not created; an index with the same fields already exists ?

  The SAP error message FKKBIX086 indicates that there is an attempt to create an index in the database, but an index with the same fields already exists. This can occur in various scenarios, particularly when working with financial documents or when trying to optimize database performance.
  Cause:
  
  Duplicate Index Creation: The most common cause is that the system is trying to create an index that already exists in the database. This can happen during a system upgrade, data migration, or when running a program that attempts to create indexes without checking for existing ones.
  Configuration Issues: Sometimes, the configuration settings in the SAP system may lead to attempts to create indexes that are already defined.

  Check Existing Indexes: Use transaction codes like SE11 (Data Dictionary) or SE14 (Database Utility) to check the existing indexes on the relevant database table. Ensure that the index you are trying to create does not already exist.
  Modify Index Creation Logic: If you are working with custom code, modify the logic to check for the existence of the index before attempting to create it. This can be done using SQL queries or by leveraging SAP's built-in functions.
  Delete or Adjust Existing Index: If the existing index is not needed or is incorrectly defined, you may consider deleting it or adjusting its definition. However, be cautious with this approach, as it may impact system performance or functionality.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide guidance on index management.
