The field catalog is a table which contains information on the fields to be displayed on the ALV output.

Subroutines are procedures that we define in an ABAP program and can be called from any program. Subroutines are normally called internally, i.e. called from the same program in which it is defined. But it is also possible to call a subroutine from an external program.

An ALV report is created using the standard function modules provided by SAP.
