* There are a number of ways to create a fieldcat.
* For the purpose of this example i will build the fieldcatalog manualy
* by populating the internal table fields individually and then
* appending the rows. This method can be the most time consuming but can
* also allow you more control of the final product.

* Beware though, you need to ensure that all fields required are
* populated. When using some of functionality available via ALV, such as
* total. You may need to provide more information than if you were
* simply displaying the result
* I.e. Field type may be required in-order for
* the 'TOTAL' function to work.
