Table - "Is being loaded"

Hi!. We are having some problems with the proccess that loades the Teradata Tables through different SISS (SQL Server Integration Services) ETLs. These proccess run daily and something it comes an error when loading. We try to run a select query through the table and it appears the "The table is being loaded" error.

What can we do in order to avoid this error?.

Thanks in advance.
