Network Number Search Help

Hi All,

Transaction cn23 - Network Number has search help to search by short text called network (General).

This search help is case sensitive.

It has 2 search parameters AUFNR & KTEXT.

Values entered in KTEXT are case sensitive.

For e.g if I enter 'set', it returns 2 records. For 'Set' returns 400 records and 'SET' returns 100 records.

How to make this parameter case insensitive?

Or has any one developed customised case insensitive search help for network number - search by short text?

Regards,

Pratibha
