    Hi,

    To create index on DSO

    GOTO DSO>Rightclick>change-->under Nav attri option u wil find Indexes->There you can create indexes.

    When you activate DSO, the system automatically creates an index based on the keyfields. Thsi is called Primary Index.

    Primary Inedex is created automatically when a table is created in the Dataabase.

    You can create Inedex on your own to improve performance, these are called Seconadary Indexes. This is necessary if the table is frequently accessed in a way that does not take advantage of the sorting of the primary index for the access. Different indexes on the same table are distinguished with a three-place index identifier.

    We will take one example:

    suppose we have one DSO and we have primary key as customer number, calendar day. lets say these are unique. and lets say if you want to run queries frequently where u select data based on Customer area and customer type.

    In this case we can create secondary index on customer area and customer type.

    Now if we run query, instead of having to read every record, it will use index to select records which contain Customer area and customer type.

    Here query saves time.

    Regards,
