Spool space is used for intermediate results/sorting/answer set.
When you click on "Tables" a query will be submitted to retrieve that information from Teradata's system tables, either a "SELECT ...FROM dbc.TablesV" or "HELP USER premtest2". Both requires spool space to be processed, dbc's has unimited spool and premtest2's 100kb is definitely not enough.
Depending on the size of your tables and the complexity of your queries you might start with at least 500MB spool:
MODIFY USER premtest2 AS SPOOL=500e+06
