CRM business activity E-mail

Dear Experts,

We are trying to create E-mail by navigating through following path

Salespro role: Activity & Cases (Work Centre) : Create E-mail (Logical Link)

But no transaction is getting displayed. We have seen settings in standard transaction type 0005 E-mail, where business activity category is 401 E-mail. We have also created Ztransaction as copy of 0005 and also seen allowed channels and other transaction type settings required for transaction. But we are not able to see any transaction when we open business activity (Create E-mail).

Please guide.

Thanks and regards

Pankaj Kumar
