How to Control Users to edit

[dolphine4u]

Hi Experts,

Need your help pls


I have an excel with below info in A, B, C & D columns

A B C D
Sulphonator InvoiceNumber Ext.Qty Req.Qty
Anil 12345 100
Kumar 34567 78
Sam 93748 56
Anil 823423 12
Sam 8918 786

My requirement is that i have placed this excel on shared drive and given access to users mentioned in column A.
If Anil opens the workbook he should be only allowed to edit column D where his name is in column A and reset cells should be locked / should not allow to be edited.
Ex: Anil name is seen in Sulphonator column in line 1 & 4 so he should only be able to enter Req.Qty in row 1 & 4.

TIA
