SAP Buffer and Memory History: Heap used and Heap Total

[Former Member]

Hello Experts...

First post and so hope I am doing things as expected

I need to adjust (lower) the amount of memory to be used by a system. To do so I want to check the amount of extended and heap memory used through the transaction ST02 and then selecting History. When looking to the EM and Heap usage I see two columns listed for the Heap; Heap used and Heap total. Can anyone please tell me what the Heap total column is showing me? I expected this to show the value that I have configured for abap/heap_area_total but it does not match the value for this parameter (it is lower). In addition, the value listed in the history for the heap total changes from one day to the next (lowest listed 284.664 and the highest listed being near on 2GB). So any idea what information this column is providing? Thanks!!

Hi David,

Heap Used will give the current usage.

Heap total will give the maximum used/total used heap for that particular day. this value should not be greater than the configured heap abap/heap_area_total.
