Unable to replicate the Vendor Master Records

Hi I am using the transaction BBPGETVD to transfer the Vendor Master Records from R/3 ro SRM...but could not able to transfer it as I am getting an error "Organizational unit -

does not exist; check entries", even through I have created Organisation Structure for Vendor also. I have maintained all the relavent parameters in the Attributes.

The following attributes I have maintained: System Alias for Accounting Systems, Company Code, Local Currency, Current ITS for an External Partner, Accounting System for Vendor, System Alias for Vendor.

Can any one tell me is there any other parameters to be maintained or where I am going wrong.

I am working on SRM5.0.

Thanks and Regards
