Subject:      Take both sets of two data sets

Hello,

I have two data sets and want to create a new data set. The both data sets
have the same columns, *but* in some cases (not in all) I must read in the
rows of both data sets. So, I think, that a merge doesn't help me, does it?.

Here is an example:

Set 1
prod.-code  valid date
----------  ----------
ABCDE       20020101
DEFGH       20020101
GFHGH       20020101

Set2
prod.-code  valid date
----------  ----------
ABCDE       20020101
DEFGH       20020201
GFHGH       20020101

The result should be a new data set with
prod.-code  valid date
----------  ----------
ABCDE       20020101
DEFGH       20020101
DEFGH       20020201 <-- new
GFHGH       20020101

Has anybody an idea how I can solve that problem?
Thanks a lot in advance.

Joerg
