Hi folks,

How to find out the initial amount of memory allocated to the internal table?

Thanks in advance,

Cheers,

while declaring the internal table the number u specify in occurs stmt gives the memory allocation

begin of itab occurs 1,

end of itab.

in this case memory for one record is stored and can b increased dynamically with population of records.

if its 0 then a default of 8kb memory is allocated initially..and can b further increased...

Hi,

in debugging, select in menu:

Goto - status display - memory use.

There you can see current memory consumption.

reward if it helps..

Hi,

Use

DATA: memory type i.

DESCRIBE TABLE itab OCCURS memory.

write: memory.

Here "memory" will have the initial size of the internal table.

Hi Sriram

check the occurs parameter for internal table 0 or 10.

hi sriram

Actually internal table by default occupies 8kb of memory...if u give occurs 1 then it occupies 8+1kb and so on...

for eg...

data : begin of itab occurs 0,//takes 8kb of mem

matnr like mara-matnr,

end of itab.

you cant see the memory allocation since it is allocated dynamically duraing runtime....

REWARD IF USEFUL....

At the time of declaring the internal table, you say either occurs 0 or number like that. ...occurs 10 or occurs 100.....

The number here is the lenght of the internal table at the time beginning or first memory allocation time. However specifying long numbers unless required is not advisable, because this consumes memory in vain in most cases.

Reward if helpful.

Thanks.

hi sriram,

1.just put a break point on your AT SELECTION SCREEN "select" querry and go to debugging mode...

2.in that SETTINGS----> MEMORY DISPLAY ON/OFF(there tick MEMORY MONITORING and press SAVE)...

3.click TABLE in the debugging mode...type your internal table name and start normal debugging...

you can literally view the memory occupied by your internal table....

here the memory allocation status for any internal table is shown only when the debugger debugs atleast a select querry.

there is an easy formula for calculating memory

occurs * size of the line of the internal tale

this value is in bytes

u can get the size of the internal table by describe statement in sy-tfill.

if ur occurs is 0 then the size is 8kb
