Importing data into a report

Importing data into a report

Hi,

Im trying to import data into a report. One of the fields in the report is "Users" which in the form is a lookup field (Which looks into another report to pull all the users we have listed in there and displays as a dropdown in the form. However, when trying to import data from CSV into the 1st report it cannot fill in the Users field (I presume because it is a lookup field). Is there a way around this? Most of the Users should match up anyway with the report that pulls the users.

Thanks
