Help With Compare Two Excel Sheets And Merge

Hello,


I have two sheets (sheet1, sheet2), and column "A" being the master identifier for both sheets. I need to compare both sheets, and what ever is common between both in column "A", I need to copy the what is in the column "D" cell in sheet1 to the corresponding "D" cell in sheet2.

Thank in advance with any help.


Thank you,
DB
