Memory Size in Select statement.

[Former Member]

Hi,

We have a problem in executing the program. The code fetches millions of records for processing, due to this , the Dump occured. Any way to fine tune the Code to split the file and process the contents of it.

The Code :

select * from zglob_avail into table gt_zglob_avail.

lv_count = sy-dbcnt.

loop at gt_zglob_avail.

if gt_zglob_avail-offer_package is not initial and

gt_zglob_avail-good is not initial.

.

.

.

. endif.

endloop.

The Dump :

Roll..................... 16128

EM....................... 595179824

MM Used.................. 572595736

MM Free.................. 14183512

Depending on your needs:

1) Add a WHERE clause to reduce the recordset and process in "chunks"

2) Add an UP TO x ROWS to reduce the recordset and process in "chunks"

Hi,

Use field groups instead of internal tables.

Ex:

FIELD-GROUPS:x_database.

INSERT: x_fld1

x_fld2

x_fld3

INTO x_database.

move 1 to x_fld1.

move 2 to x_fld2.

move 3 to x_fld3.

EXTRACT x_database.

Hi,

1.

Instead of using SELECT * , specify only the fields which are required.

eg. SELECT MATNR

MAKTX

from makt

where.....

2. In the WHERE clause specify the condition OFF_PACKAGE Not initial and good not initial.

3. This would avoid the If condition inside the loop.
