If you intend to learn CA-7 (and there is no one in your organization to teach you), you need to read the documentation provided by CA. If your organization is licensed to use the product, all of the material may be downloaded free from CA Support.
If you find something in the CA documentation that is not clear, post what you found and your doubt about it.
Someone may be able to clarify.
We are not able to provide product training. . .
Hope this helps,
