Viewing - Internal Table Memory Used?

[Former Member]

Hello all,

I could understand the difference between Internal Table with occurs 0 and internal table with type declaration...

correct me if i am wrong, occurs 0 declaration occupies 8kb memory and header line 256 bytes...

But what i could not get is...

Where can i view this internal table runtime memory usage?? Should i have to check that in some transaction???

If that is the case, what transaction i should look at?? Can i view this in debugging mode??? I tried GOTO -> STATUS DISPLAY -> MEMORY USE and i have tried even SETTINGS -> MEMORY MONITORING ->MEMORY DISPLAY ON...Nothing worked..

I have searched a lot about this in SDN....But could not come to a conclusion......

Waiting for your replies....

Hi ,

You can do that in debugger and also try tcode S_MEMORY_INSPECTOR.

Also, this might help you.

To find out how much memory internal tables occupy, In the debugger , choose Goto ->Display Condition ->Memory Usage. Choose Change Settings to display a window, in which you can choose the Internal Tables button.

Hello Vasuki,

I have tried what you said here [Goto ->Display Condition ->Memory Usage. Choose Change Settings to display a window]...But memory allocated seems to be same for Internal table with occur 0 and Internal table with type declaration...

I don't have authorisation here for DBG_MEMORY_DIFFTOOL or S_MEMORY_INSPECTOR unfortunately.....

Then how to conclude, occurs 0 declaration gives low performance when compared to type declared Internal Table??

Can you please suggest me some more???

Hi,

to get the internal table used in the ru time you goto> classical debugger> goto->status display>memory consumption.

In tab memory use you will got all the table used by the program.
