Subprograms are included in the global part of the routine using an INCLUDE

You cannot use INCLUDES.

You can convert these subprograms in the following ways:

1. Convert the subprograms into global, static methods.

2. Create a subroutine pool in the ABAP editor and execute these subprograms using PERFORM SUBROUTINE.

3. Define a function module that has the logic of the subprogram.

Function modules, methods or external subprograms can be called in the local part of the routine.

STATICS statement

The STATICS statement is not permitted in instance methods. Declared static attributes of the class can be used with CLASS DATA instead.

Addition OCCURS when the internal table is created

The OCCURS addition is not permitted.

You use the DATA statement to declare a standard table instead.

Internal table with header row

You cannot use an internal table with a header row. You create an explicit work area with the LINE OF addition of statements TYPES, DATA and so on to replace the header row.

Direct operations such as INSERT itab, APPEND itab on internal tables

You have to use a work area for statements of this type.
