Hi ABAP Gurus,
I am new to ABAP. I am facing a confusion whether to use INITIAL SIZE option while defining my internal table. Some existing codes use OCCURS. So my questions are:
1. Difference between INITIAL SIZE and OCCURS?
2. When should I use INITIAL size. Are there any specific cases?
3. Is there any performance issue if I use INITIAL SIZE?
4. Why OCCURS is not recommended?
5. Is it true that if I use OCCURS then the internal table is created with header line? With INITIAL SIZE header line is not created?
6. What is the difference between INITIAL SIZE 0 and INITIAL SIZE 10?
Thanks
Gopal
