Hello Pradeep,

As mentioned by the experts above,memory issues in SAP is a very generic term. Please provide some more details about the problem. Are there are any system dumps ?

Hi Pradeep,

What type of issues you are facing regarding memory ... Please paste logs of that issue , so that it is easy to analyze & resolve.

Normally We faces program buffer issues (abap/buffersize). For this we have to increase parameter value in RZ10 .

Hi Pradeep,

Also in you profile directory please run command sapfpar check pf=profile name

See if this gives any warnings errors on this.

Then also for the related buffering memory in query please go to ST02 perhaps attach us your ST02 screenshot with attention to hitratios.

Kind Regards,

The memory configuration you need is dependent to a large extent on your systems' workload, so it is hard to give generic advice. What memory management issue are you having, and how do you know about it?
