Difference in memory for functiongoups and classes

[former_member185171]

Hello,

can anyone give me more information on how function modules and objects behave (differently) within memory. Does the used memory lasts longer for one or for the other? Do they reside in the same memory.

For performancetuning we think of wrappig database calls by a class or a functionmodule. In it we would like to collect the made calls within an application. If we store these made calls in some table, will it survive longer in a class (a singleton e.g.) or in a functionmodule?

Thanks a lot.

Hello

With regard to ABAP memory usage shared memory would be the location and when function module is completed then after exporting the value <x> or tables by function module ABAP memory will be released.

I hope this helps explain the functions somewhat.

Regards.
