Difference between INITIAL SIZE and OCCURS

597 Views

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
