Macro for pulling and updating data from one workbook to another

Dear Sir,

I have two workbook.In 'Entry'Workbook where data is filled up daily in different blank cells.In 'Report' workbook,exactly, I want to pull and update the data .The format is same.Then those changes if possible must be shown in a separate sheet.Since the data is very large,I cannot track where the changes has been made in 'Entry' Workbook'.In order to know the changes in cells,I require this on daily basis.Hence I require two things-

1.VBA Code/Macro for pulling & updating changes to 'Report' workbook from 'Entry'Workbook .And only those changes that should be ignored that has been made by me in 'Report'Workbook

2.Changes made in 'Entry'Workbook must be summarised in a separate sheet in 'Report'Workbook.

Hope this is sufficient information.If any info,kindly do let me know. I have mentioned in my earlier post too at >>>

Hope this time it could get solved.
