• What is the cause and solution for SAP error message DT982 - Table & has no indices ?

  The SAP error message DT982 indicates that a specified table does not have any indices defined. This can lead to performance issues, especially when querying or accessing data from that table, as the database will have to perform full table scans instead of using indices to quickly locate the required records.
  Cause:
  
  No Indices Defined: The primary cause of this error is that the table in question has not been defined with any indices. This can happen during the table creation process or if the indices were inadvertently deleted or not created.
  Table Design: In some cases, the design of the table may not require indices, but this is rare for tables that are frequently accessed.
  Database Configuration: There may be issues with the database configuration or settings that prevent indices from being created or recognized.
  
  Solution:
  
  
  Create Indices: The most straightforward solution is to create indices for the table. This can be done using the Data Dictionary (SE11) in SAP:
  
  Go to transaction SE11.
  Enter the name of the table and click on "Display".
  Switch to "Change" mode.
  Navigate to the "Indexes" tab.
  Create a new index by specifying the fields that should be indexed.
  Save and activate the changes.
  
  
  
  Review Table Usage: Analyze how the table is being used in your application. If it is frequently queried, it is advisable to create appropriate indices to improve performance.
  
  
  Consult Documentation: Check SAP documentation or consult with your database administrator to understand the best practices for indexing in your specific scenario.
  
  
  Performance Testing: After creating indices, perform performance testing to ensure that the changes have positively impacted the query performance.
  
  
  Related Information:
  
  Index Types: Understand the different types of indices (e.g., primary, secondary, unique) and choose the appropriate type based on your requirements.
  Database Performance: Indices can significantly improve database performance, but they also come with overhead in terms of storage and maintenance. Regularly review and optimize indices based on usage patterns.
  SAP Notes: Check SAP Notes for any specific recommendations or known issues related to the table in question.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SE11 (Data Dictionary), SE14 (Database Utility), and SE80 (Object Navigator) for managing database objects.
  
  By addressing the lack of indices, you can improve the performance of database operations related to the affected table and resolve the DT982 error message.
