If a user tries to open a Workbook that is already open, then they normally get a message saying that the File is locked by a certain user and would you like to open the file in Read only mode. However, you can open a workbook in shared mode by following these steps. First open the file that you want to share, then once the workbook is open, go to the Tools menu and choose Share Workbook from the drop down menu. The Share Workbook dialog box will now appear. To enable sharing, you simply click once on the Allow Sharing check box, so that it has a tick. Once you do this other people will now be able to use your Excel workbook whilst you are working on it.
Instead of listing the items on a paper list the items can be just as easily listed on a spreadsheet which will add up the items as required without the requirement to double check the adding up is accurate. Such a list has a history in accounting term as a sales day book and a purchase day book. To achieve the required analysis of sales and purchases all that is required is to write into the top of each of the spreadsheet columns the titles of the analysis headings required. Then repeat the value of each transaction in the total column into the analysis columns. Use the spreadsheet technology to add up each column and you have an effective bookkeeping spreadsheet. Preparing such a bookkeeping spreadsheet might and often does suffice the needs of the smallest business enterprise and is a close step towards achieving a valuable tool for this purpose, bookkeeping software. Bookkeeping software can be as simple as a home produced spreadsheet but with additional facets that can have significant financial benefits to the business.
