Query about User exit ITOB0001 in Tx. IE01/IE02/IE03

Hi All,

We have implemented user exit ITOB0001 for transaction IE01. We have written code in

- EXIT_SAPLITO0_001

- EXIT_SAPLITO0_002

and

- Screen 1080 ( SAPLXTOB 1000 )

But, the additional data tab with custom fields is not being displayed in transaction IE01 / IE02 / IE03.

What additional steps are required ? Am I missing some steps ?

Regards,

Ashish
