How to restrict printing smartform at VF02 when creation date (ERDAT) is not older than 01.01.2019?

Hi experts,

I am new to ABAP. I have a requirement where I have to disable/restrict printing invoice at VF02 when creation date (ERDAT) is not older than 01.01.2020. Normally we do VF02 -> enter billing doc date -> at menu bar click billing document -> Issue output to -> print preview. I have to restrict this print preview or the generation of smartform. I searched on google but not getting any particular results. It will be best if I get step by step solution to this requirement. Please help ASAP.

if I write the required query as an If .. Endif statement inside lf_fm_name block, will it work?
