Hi Raj,
Yes it can be by using the SAP and SuccessFactors integration add-on (Talent Hybrid add-on). TXT files are exported from SAP, so you probably want to either export the file to a place where a middleware can pick the file up and send to SuccessFactors or define the SuccessFactors SFTP as a logical destination in SAP to place the file directly on there.
Best regards,
Luke
