Hi!
I assume that the error is not correct and that reference exist, correct? If so, can you provide more details about the setup of your migration using the SPMT

@Juan Carlos González Martín 

In our on-premise SharePoint, we using some list as a global list in Top-level site.

we are tried to move the one sub-site document library to office 365 Sharepoint.

we don't want all document libraries so that we are tried to move a particular document library.

How we can properly do this process?

If you don't move also those lists, you are not going to be able to migrate due to that error unless the migration tool provides a way to skip the lookup column or map to a different one

@Jey_Ganesh Check Weather those lookup lists are available in the current site or site columns. If they are make necessary actions and try again.

For complete migration of site including Metadata, Versions history, approval status and many more please refer this. Saketa SharePoint Migrator contains many more features like incremental migration, user group mapping, managed metadata migration and etc.
