Extract SM20 data to BI

Hi Experts,

We have a requirement that we need to send SM20 audit log data from ECC to BI .I am form Basis team and don't have much idea about data extraction into BI system.Please let me know if it is possible to extract flat file data (from file system /usr/sap/<SID>/D*/log/audit*.log) to BI system.If possible send me some good link which I can refer.

Thanks
