Hi,

I am afraid I didn't explain my problem clearly enough.

Please let me describe it once again.

I have two sheets.
Records in both sheets have identifier (in the first column) which
is unique.
In Sheet 1 there are all records (=all identifiers) whereas in
Sheet 2 there are only some of them.
All identifiers which are in Sheet 2 are always also in Sheet 1.

The below is just an example where Sheet 1 contains only 5
records and Sheet 2 contains only 3 records.

In the example Sheet 1 contains records (rows) with identifiers
X1,X2,X3,X4,X5 (in column K0) and data in columns K1,K2,K3,K4.
In the example Sheet 2 contains records (rows) with identifiers X2,X4,X5
(in column K0) and data in columns K5,K6,K7.
K0,K1,K2,K3,K4,K5,K6,K7 are names of the columns.
I want to have a Sheet 3 (or updated Sheet 1)
containing records (rows) with identifiers X1,X2,X3,X4,X5 (=all records)
(in column K0) and (all) columns K1,K2,K3,K4,K5,K6,K7
where data in columns K1,K2,K3,K4 are from Sheet1
and data in columns K5,K6,K7 are from Sheet 2.
It seems to be a kind of combining two sheets where the first sheet
contains all records and the second sheet contains only some of them.

I think this is a good example: Sheet 1 contains data for all employees
like family name, given name, date of birth, address etc.
The family name is the identifier.
The Sheet 2 contains only data for some of the employees connected
with their membership in any association like date of admission, position, etc.
Of course the Sheet 2 must also contain family name of each personin the
sheet which is the identifier.
Not all of employees were admitted to the association.
I need to have all data in one sheet.

Please help me. It is urgent.

Regards
