Import record-automatic

Hi all,

I am facing an interesting issue.

I have imported one record using IMPORT SERVER as automatic by placing the xml file in the ready folder.

That record have the partner number as "50001" with the name " rahul".

It was imported successfully.

After that i have imported another record having the partner number as "50001" with the name " vijay" (in this record i changed the name only noy partner number).

And i placed it in ready folder , its imported. i can see the record in the archive folder with my changes.

But in the data manager i am seeing the old record only.

What is the problem in this?

Why the modified record having the same partner number is not uploading?

Thanks in advance.

Vijay
