What is table index in SAP BC-ABA - ABAP Runtime Environment?

SAP Term: table index

• Component: BC-ABA

• Component Name: ABAP Runtime Environment

• Description: Index of an internal table managed by the ABAP runtime environment. There is a primary table index for index tables and secondary table indexes for the administration of sorted secondary table keys. The row numbers of each table index start at 1 and continue serially and without gaps to the current number of rows in the table. If necessary, the conversion from a physical index to a logical index is made. Changes to a logical index need more runtime. The logical index is created when a row is inserted before another, the sequence of the table rows changes, or a table row of the table index other than the last row is deleted.

• Key Concepts: 
  Table index is a feature of the ABAP Runtime Environment in SAP that allows for faster access to data stored in tables. It is a type of index that is used to quickly locate and retrieve data from a database table. The index is created by the system and is based on the primary key of the table. 
  
  How to use it: 
  Table indexes are automatically created by the system when a table is created. They can be used to quickly locate and retrieve data from a database table. To use a table index, you must first identify the primary key of the table. Once you have identified the primary key, you can then use the index to quickly locate and retrieve data from the table. 
  
  Tips & Tricks: 
  When creating a table, it is important to consider which fields should be used as the primary key. This will help ensure that the index is created correctly and that it can be used efficiently. Additionally, it is important to keep in mind that indexes can become fragmented over time, so it is important to periodically check and maintain them.
