Only few Transactions are visible in GUI

Hi Gurus,

In SAP CRM 7.0 GUI screen , In current settings, it shows only few 'z' transactions, and when we configure any new "z" transactions or "activate" any other standard sap transaction, it is not visible there,

As far as we know, this visiblity can be controlled by two ways-

1.At transaction type detail- set "Active" check box.

2.Channel- "GUI CRM webclient UI", this should be maintained.

(is there any other way of controlling visibility..????)

And in our case both holds true.

still we are not able to see certain existing and new transaction types- in our create window.Please see screen shot below:-

how can we make all transaction types visible here in create window..?

Please help us.

Thanks,

G.One
