Smart SAP Assistant

• What is the cause and solution for SAP error message /SDF/DB6141 - Table &1 has more than &2 percent of overflow page accesses -> REORG ?

  The SAP error message /SDF/DB6141 indicates that a specific database table has a high percentage of overflow page accesses, which suggests that the table's data is not being stored efficiently. This can lead to performance issues, as accessing overflow pages is generally slower than accessing regular data pages.
  Cause:
  The primary cause of this error is that the table has a significant number of overflow pages. This situation can arise due to several factors:
  
  Frequent Updates: If the table is frequently updated, it may lead to fragmentation and the need for overflow pages.
  Large Data Volume: A large volume of data being inserted into the table can exceed the allocated space, causing the database to use overflow pages.
  Inadequate Table Design: Poorly designed tables or inappropriate data types can lead to inefficient storage and overflow conditions.
  
  Solution:
  To resolve this issue, you should perform a reorganization (REORG) of the affected table. This process will help to reclaim space, reduce fragmentation, and improve performance. Here are the steps to follow:
  
  
  Identify the Table: Determine which table is causing the issue by checking the error message for the table name (&1).
  
  
  Analyze the Table: Use transaction codes like SE14 (Database Utility) to analyze the table and check its current state.
  
  
  Perform a Reorganization:
  
  In transaction SE14, select the table and choose the option to reorganize it.
  Follow the prompts to complete the reorganization process.
  
  
  
  Monitor the Table: After the reorganization, monitor the table's performance and check if the percentage of overflow page accesses has decreased.
  
  
  Consider Table Design: If this issue recurs frequently, consider reviewing the table design, indexing strategy, and data types to optimize performance.
  
  
  Related Information:
  
  Database Maintenance: Regular database maintenance, including reorganization and updates to statistics, can help prevent such issues.
  Performance Monitoring: Use performance monitoring tools to keep an eye on database performance and identify potential issues early.
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or solutions related to this error message.
  
  By addressing the underlying causes and performing regular maintenance, you can minimize the occurrence of this error and maintain optimal database performance.
