Dynamic Programming in ABAP

Dynamic programming can involve activities such as specifying the type, length, offset, number of lines, or the name of a program object at runtime. At the extreme end of the scale, the program object itself can be generated at runtime.

The following types of dynamic programming are supported by ABAP:

• Dynamic extension of internal tables and strings
• Dynamic offset and length specification (in MOVE , WRITE TO , formal parameters, and field symbols)
• Dynamic specification of program object names (the name of a table, modularization unit, sort criterion, control level criterion, and so on)
• Dynamic specification of type and data declarations

The following techniques can be used:

• Dynamic language elements
• Generating programs from within programs
• Field symbols
• Runtime type services
