Steps to Reproduce

Hello Team,
I have an issue with importing prefixes. I want create prefix with link to vlan_group, vlan and site.
But I could not import prefix if vlan does not directly linked to the particular site.
I have a few vlan_groups:

Name,Scope type,Scope,VLANs,Description
BB,,,16,Backbone Networks
BR,,,15,Branches Networks
CO,dcim.sitegroup,B,17,Central Office Networks
DC,dcim.sitegroup,A,22,Data Center Networks

But they dont have stricted links to the particular sites.
And when I try to import prefix with csv file like this:

prefix,status,tenant,site,vlan_group,vlan,description
10.131.2.0/24,active,AG,AG31-002,BR,10,AG31-002-CORP

I have an error:

row 1: vlan object not found.

Therefore I have it (vlan) within a group.
Manualy I could add it without errors. But I have to fill the row VLAN before the Site row.
Also if I create vlan linked with site then csv import goes without any problems.

Expected Behavior

When I'm adding new prefix with csv alike:

prefix,status,tenant,site,vlan_group,vlan,description
10.131.2.0/24,active,AG,AG31-002,BR,10,AG31-002-CORP

It should be imported successfully without error even if I dont have vlan linked to site.

Observed Behavior

When trying to import prefix through csv with vlan and site link

Group,VID,Name,Prefixes,Tenant,Status,Role,Description,Site
,10,Corporate,,AG,Active,,,AG31-002
BR,10,Corporate,,AG,Active,,,

import

prefix,status,tenant,site,vlan_group,vlan,description
10.131.2.0/24,active,AG,AG31-002,BR,10,AG31-002-CORP

If we dont have vlan linked to the site we have an error

row 1: vlan object not found.

If we use

prefix,status,tenant,site,vlan_group,vlan,description
10.131.2.0/24,active,AG,AG31-002,,10,AG31-002-CORP

Everything goes well cause we have vlan linked to the site.

I posted a similar issues few weeks ago : #9279
This is an expected behavior, your VLAN has to be in the same site as the prerfix.
