Hello Shark,

For the buffer, memory related parameters, you could use the following :-

[HS] = size of the physical main memory

[PM] = value of the profile parameter PHYS_MEMSIZE (standard value=[HS])

[BE] = maximum possible number of users (calculated from [PM])

<b>Standard values for zero administration memory management</b>

Profile parameter

Standard 32-bit

Standard 64-bit

Unit

As per the link - , it suggests the following needs to be changed :-

Set the system profile parameters

- abap/heap_area_dia

- abap/heap_area_nondia

to a maximum of 217027232. Then reduce the value by 10.000.000 to be on the safe side. Then restart the SAP System.

For futher refrence, please follow the links as below :-

Do let me know in case of any doubts.

Thank you.
