Combining 2 different pgm

Question

Is there a way to create a new program by adding few lines dynamically?

Answer 1

yes, You can create a ABAP program dynamically & can insert few lines of code in that.here is the process
1)we must create an internal table first. i.e., internal table with a single column of type character and a row width of 72.
DATA: code TYPE TABLE OF rssource-line.
type of an editor line: rssource-line
2) append required ABAP code to this Internal table
APPEND  'REPORT ZDYN1.'
         TO code.
APPEND  'WRITE / ''Hello, I am dynamically created!''.'
         TO code.
3)
INSERT REPORT <prog> FROM <itab>.
If a program with this name does not already exist, it is created with the following attributes:
Title: None
Type: 1 (report)
Application: S (basis)
The new program <prog> is stored persistently on the database but is not assigned to a package. It is therefore not affected by the transport system.
Pl NOTE that : If a program with the name <prog> already exists, its source code is replaced with a new one from the internal table <itab> without prior warning. All other attributes remain intact.
FOR CHANGING EXISTING PROGRAMS :
you can change the existing ABAP program.
1) first read the total ABAP report into <ITAB>
READ REPORT <prog> INTO <itab>.
2) add your required code to this <ITAB>
3) now u can insert the new changed code
INSERT REPORT 'ZDYN2' FROM CODE
