Problem uploading email address while uploading in fk02

Dear experts,

I am running a BDC to upload some vendor details for already existing vendors. All the fields are getting uploaded except "email ID"

While running the BDC the email field gets copied into the screen from tab file also. But it is not getting saved in LFA1 table.

Please guide.

Is there any other way to upload email ID separately??

Warm regards,

Sumit Nene.
