• What is the cause and solution for SAP error message HH021 - Reorganize the specified table ?

  The SAP error message HH021, which states "Reorganize the specified table," typically indicates that a database table has reached a certain threshold of fragmentation or has accumulated a significant amount of obsolete data. This can lead to performance issues and may prevent further data operations on that table.
  Cause:
  
  Table Fragmentation: Over time, as records are added, modified, or deleted, the physical storage of the table can become fragmented. This can lead to inefficient data access and slower performance.
  Obsolete Data: Tables may contain a large amount of obsolete or unnecessary data that needs to be cleaned up.
  Database Size Limits: Some databases have size limits for tables, and if a table approaches this limit, it may trigger the need for reorganization.
  System Performance: High levels of fragmentation can lead to degraded performance, which may trigger this error.
