In From Column Mapping panel, the information at
the top of the panel shows you the current mapping. In the figure,
the To column is RID. There is currently no From column shown
because there is no column in the From template with the same
name.
To change the From column, enter S against
the new From column. The information at the top of the panel
changes immediately to reflect the new mapping. For example, if you
enter S against column #6 (PHONENO), the information
at the top of the panel changes:

From Db2 object . : DSN8810.EMP
To column . . . . : #15 RID
From column . . . : #6 PHONENO
and the Template Mapping
panel also changes to show that PHONENO is mapped to RID:

There is now an entry in the From column against RID.
To remove the current mapping for a To column, enter S against Delete From
column on the From Column Mapping panel for that column. For
example, the Template Mapping panel shown in Template Mapping panel shows that the To column
BONUS is mapped to the From column BONUS. To remove the mapping
for BONUS (so that it is not mapped to any From column):
On the Template Mapping panel shown in Template Mapping panel, enter S in the Cmd field
against column #13 (BONUS).
Enter S against Delete “From column”. Figure 2. From Column Mapping panel showing Delete “From
column” selected
