What does a table with OCCURS 0 in ABAP mean?

Question

I’m starting out in the SAP world and found an internal table declared as follows:

DATA: it_buscar TYPE ty_ztabela OCCURS 0 .

What is that OCCURS 0 siginifica?

Answer 1

Eduardo’s answer is correct, but it is an obsolete way, whenever creating a table it is better to use TYPE TABLE OF 'here your table'

Answer 2

Occurs 0 Specifies how many rows the table can have, when set to zero you can have as many rows as needed.
