Hello SAPLearners, in this blog post we will learn about Extension Index in SAP ABAP
What is an Extension Index?
Extension Index are nothing but secondary indexes for the SAP standard tables.
When you create a secondary index, SAP considers it as a modification to the table. But when you create an Extension index we are not actually modifying the standard table rather enhancing it.
This concept is introduced in new Enhancement framework netweaver version 7.0
What are the drawbacks with the normal Secondary Index creation?
Even though you have created the secondary index in customer namespace, these will not be available when you upgraded the system with new releases. We have to again create the secondary index after completing the upgrade activities.
What benefits we get with Extension Index?
These indexes are upgrade protected. We can still able to see these indexes after system upgrade.
Lets see how we can create an Extension Index for standard tables. In this tutorial i will create an extension index for standard table VBAP.
1. Go to SE11, select VBAP table and click on “Indexes”.
