Splitting flat file data

[Former Member]

I want to store the flat file data for temporary purpose and as a backup also, but its size is so huge that processing them at one instance is a difficult task. Is there any 'Z' program that will split the records puts it in a new file. Anyone please give an idea and your answer ll b rewarded with maximum points if it helps me on this issue.

END OF input.

DATA: i_mara_tab LIKE TABLE OF input WITH HEADER LINE,

i_mara_temp LIKE TABLE OF input,

w_mara_tab LIKE LINE OF i_mara_tab,

v_split(4) TYPE n VALUE 1,

v_count(4) TYPE n VALUE 1.
