ABAP Extension Index

ABAP Extension Index
We already know that Index is very crucial for the performance. SAP offers two way to create index in t-code;s11.

- Create Index : this is classical and usual way
- Create Extension Index : it
s same function with Create index, but this kind of index will not be overwritten in SAP upgrade.



When doing SAP upgrade, there is a possibility to delete or overwrite the current secondary index customer created for performance issue. This issue might make a critical performance issue. Even though we found the root cause, it would take very long time to create index in production server because index is small copy of table.
When creating index, Extension Index protect this risk in advance.
