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.
- 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.
