How to assign contact person with user id to vendor via upload
We have successfully uploaded external business partner (Vendor) from ECC6 to SRM5.0 via BBPGETVD. So vendor is available in PPOMV_BBP.
Now we would like to assign the contact person with user ID to this vendor so that he can logon to our system and update Bid.
If we create contact person (employee) via "Manage Business Partner", system provides the option to create contact person and User ID under "Employee for Business Partner".
But we can create contact person one by one, if our client have 600 vendors from ECC and already transferred to SRM.
How to rapidly create and assign contact person to all vendors ?
Who have any ideas for upload via text file or excel sheet please advice me.
