Hi there rajesekar, welcome here to Filipino UK
It seems that the evidence you submitted did not support the UKBA Financial Requirement
Based solely on what you've divulged I would suggest appeals is not a route for you.
My initial advice would be this:-
1. If you actually submitted documentary evidence that supported the application and relevant immigration rules, then include copies and explanations in a letter to the ECM (Entry Clearance Manager) requested a reconsideration of the ECO decision based on an error in reading submitted documents.
2. Gather together all the required evidence (pay slips, bank statements, Employer letters etc) compliant with immigration rules (including missing documents) and re-apply.
If you have any specific questions don't be shy to ask for clarifications
Hope that helps with your situation.
BTW, do you currently comply with the Financial Requirements?
