I started my career with SAP Basis and now after completing more than 5 years i really enjoy working as a Basis Consultant .The most important aspect for SAP Basis is troubleshooting when an issue occur .Here are some of the points and observation I want to document which can be helpful for a new resource in this practice.Any thing that occur has a logical reasoning nothing happens on own.So when an issue occurs we need to find what has changed whether there i a transport or any activity that has messed up.We have to not to be stubborn in our thinking for fixing an issue .We have to see over all perspective of an issue and to start troubleshooting from Scratch .
Also i think we should not trust on any one and double check every logs ,connection ,user ids and basic things.At some time in my career i have observed issue at a very ground level and wasting my time for more than 3-4 days.So initially we have to check and start from Basic level.We need to confirm from our level every thing rather than relying on others.Our motive should be positive and seeing from every perspective.
Issue can be at any level :-
If we see any recent activity on these level then we can check logs at these first.
Also the important point is we have to be positive, energetic and never give up attitude while fixing an issue .At times in SAP Market i see people like only installing a SAP System like a binary software .But our profile is to Maintain SAP and keep it up and running 24*7.
