Kernel Upgrade Impact on ABAP perspective ?

[former_member194669]

We are planning for Kernel upgrade. I like to know what kind of impact on ABAP point of view.

My question is after the upgrade what are things i may needs to check from abaper perspective ?

I don't know is right to ask this question in abap general forum. may be our abap friends have something to share.

aRs,

Not so sure but we faced a problem once after the kernel upgrade.A program which is using FTP was not wokring as there were some changes done at the server level after kernel upgrade like changing the Server name/Ip etc.May be a Basis guy can throw more light on this topic.

it succesfully without any issues for us.

@gautam : i've read that before kernel upgrade we have to use "SGEN" transaction to generate objects with available load and then after kernel upgrade is done we have to regenerate objects from last generation..
can you please explain why do we need to do this...
as per my understanding it has got to do something with ABAP consistency....
but why excatly this is done..can anyone tell..

This is done to reduce the time to load the abap programs so that it's already bufferred up.
