lead transaction hide tabs

Hi,

For a Transaction Type ZSBB (lead transaction), a number of tabs are availabe in Transaction data which the client does not want. i.e All the tabs are not required. We need to disable/ hide the tabs...

How can I do it..

I tried transaction screen control but now im getting the following error

function code LEAD_START is not available for program SAPLCRM_LEAD_UI. Any idea why this error and how to resolve it...

Advance thanks
