I want to find values of column B of Worksheet "NAT" in
the Column C of Worksheet "Policy". (Please note that
there is Many-to-many relationships between
Worksheets "NAT" to "Policy") Where we find the value, I
want to put a corresponding value from the column A of
Worksheet "NAT" into the column B of worksheet "Policy".

However, since the relationship is many-to-many, I have
to find the values in the column C from Wkst "NAT" to
Column D in the Wkst "Policy" for differentiation. In
some cases, instead of value, the alias (group) is
mentioned in the Column D of wkst "Policy". For such
cases, I have to find the value of Column C from
wkst "NAT" to the Column B (String format) of the Wkst
Groups.
