Hi SAP-ABAP Experts .
I have created a internal table like this
TYPES: BEGIN OF it_pa0001,
ename TYPE pa0001-ename,
END OF it_pa0001.
(1) DATA: it_pa0001 TYPE STANDARD TABLE OF it_pa0001 INITIAL SIZE 0,
(2) DATA: it_pa0001 TYPE STANDARD TABLE OF pa0001 with header line .
(3) DATA: it_pa0001 like pa0001 occurs 0 with header line .
what is difference b/t Initial 0 and Occurs 0 ????
PLease explain it .
