How much space will be allocated for Occurs 10

Question

Hello,
Kindly clarify my below queries?
1) if occurs 0 takes minimum 8 kb space
then how much will occurs 10 will take .
i.e when to use occurs 0 ,occurs 10 ,occurs 100?
2) what is the maximum number of lines an internal table can contain ?
Regards,
Rachel

Hi,
<li>OCCURS <n>. The below information answers both questions.
This size does not belong to the data type of the internal table, and does not affect the type check. You can use the above addition to reserve memory space for <n> table lines when you declare the table object.
When this initial area is full, the system makes twice as much extra space available up to a limit of 8KB. Further memory areas of 12KB each are then allocated.
You can usually leave it to the system to work out the initial memory requirement. The first time you fill the table, little memory is used. The space occupied, depending on the line width, is 16 <= <n> <= 100.
It only makes sense to specify a concrete value of <n> if you can specify a precise number of table entries when you create the table and need to allocate exactly that amount of memory (exception: Appending table lines to ranked lists). This can be particularly important for deep-structured internal tables where the inner table only has a few entries (less than 5, for example).
To avoid excessive requests for memory, large values of <n> are treated as follows: The largest possible value of <n> is 8KB divided by the length of the line. If you specify a larger value of <n>, the system calculates a new value so that n times the line width is around 12KB
