Background Verification

I have 9 years of experience in SAP domain, before that i worked in a small company in other technology but don't have pf and salary account also closed due to inactivity. I never showed that 1 year experience while changing jobs but this time I'm planning to show that experience while switching. As i don't have pf and bank statement what issues can i face while background verification and what justification should i provide. note:- i have remaining documents like payslips, offer letter and relieving letter. TIA
