Mostly, ABAP programmers doesn't care too much on the memory being consumed by the application or reports they are creating during runtime. Though, yes sometimes, memory consumption is not the main issue when comes to abap programming. But, for me, having an efficient memory allocation and management of your application is one way of showing how keen you are and not only that, it shows also how much you care to the overall performance of your SAP system where your apps resides. It starts from 1 to reach 1000 and so on. Meaning, if you don't know how to manage or to free-up even 1bit of your memory garbage, it will lead to be a problem/disaster later on. So why wait for your apps/system to crush when you can manage it right now? In this topic, I will show you the different tools available from SAP that could help us in managing memory issues and if how can we minimize and clean up some of those.
