Linking up to worksheets through Many-to-Many relationship

[BNLY]

Hi everyone, I'd like to seek help from you guys in writing a VBA code to link up two Excel worksheets, which consist of relative large volume of data. Let's say the two data lists are in the forms of the following:

Sheet 1:
Customer Key, Account Number, Balance
ID001, AC001, $100
ID001, AC002, $30
ID002, AC006, $20
ID002, AC007, $0
ID003, AC010, $500

Sheet 2:
Customer Key, Bonus ID, Bonus Point
ID001, BB001, 240
ID001, BB002, 100
ID002, BB005, 320

The required output will be placed in the Sheet 3 and it will be look like this:

Sheet 3:
Customer Key, Account Number, Balance, Bonus ID, Bonus Point
ID001, AC001, $100, BB001, 240
ID001, AC001, $100, BB002, 100
ID001, AC002, $30, BB001, 240
ID001, AC002, $30, BB002, 100
ID002, AC006, $20, BB005, 320
ID002, AC007, $0, BB005, 320
ID003, AC010, $500
...

Can the final output be generated via writting an effective Excel VBA code?

Many thanks for your help in advance!

I too am interested in the answer to this question. I'm new here and I don't know how to follow.

Will you please attach a sample Excel workbook? We are not able to work with or manipulate a picture of one and nobody wants to have to recreate your data from scratch.

1. Make sure that your sample data are REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

2. Make sure that your desired results are also shown (mock up the results manually).

3. Make sure that all confidential data is removed or replaced with dummy data first (e.g. names, addresses, E-mails, etc.).

4. Try to avoid using merged cells as they cause lots of problems.

Unfortunately the attachment icon doesn't work at the moment, so to attach an Excel file you have to do the following: just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.

Please pay particular attention to point 2 (above): without an idea of your intended outcomes, it is often very difficult to offer appropriate advice.
