Index &V1& is not a clustering index as required.

System Response
A clustering index physically organizes all the data records for a tablein the database. Access for reading and deletion is expedited by this.

Procedure
Check the database status for index &V1& in transaction SE14 ABAP/4Dictionary: Utility Database. Specify table name &V2& and chooseIndexes.... Select the index and choose Storage Parameters
. In the index list, the "OPTIONS" parameter needs to have the value "CL
USTER" under index &V1&. If this parameter is missing, create it under"For New Creation" and reactivate the index.
