I am using a SELECT query on a database table. Since the number of records in the table is very large, the program dumps due to insufficient memory. How can I solve this?

In this case you could use the PACKAGE SIZE addition in the SELECT query to process in limited amount of data, thus avoiding the memory overloads.

Eg:

SELECT *

 FROM <table>

 INTO TABLE itab

 PACKAGE SIZE <n>.

IF sy-subrc EQ 0.

*" Process the n records

ENDIF.

ENDSELECT.
