Occurs 0 will allocate one record of memeory as and when the first record in appended or inserted to the table. BY default no space wil be reserved at the beginnig..
Occurs1 will reserve space for the first record from the beginning itself. From there on, there is no much difference.
The number <N> indicate how many lines has to have the table in initialization time: i.e. when the program is loaded in memory, the space for the table depends on the initialization numbers of the records.
AT run time if the table needs more space, this'll automatically be enhanced.
When we use Occurs 0 no memory will get allocated to that internal table.
When we use Occurs 1 reserved the memory for one record.If you add more records than OCCurs number in Both cases memory will get incresed automatically.Occurs with number we will use only when we total number of records to be stored.
Ex: if you allocated memory like OCCURS 10000 and add 100 records rest of the memory will be wasted .
