Dropping Index on manage Tab...

Hi,

When we drop the indices on an InfoCube on the RSA1 - Select the Cube - Context menu (Manage) - Performance tab, does it drop the index on F table or E table.

I think it drops only on F table.

Is there any way in SAP to drop the indices on E table?

OR

It needs to be done at Oracle level.

Please let me know if any has any idea about this issue.

I will appreciate your help.

Thank you.
