Excel workbooks are complex. Multiple persons share and handle the same file. We keep mailing them to each other. Often the person who created the file has left the organization long back. There is never any documentation available about exactly how a file works.
Due to all this, it is almost impossible to remember which value is used in which formula. When you are about to change a value or add more data to existing block, it is absolutely necessary to ensure that all the related formulas are updated. If you forget to update the formula, the results shown there will be outdated and WRONG. This can hamper decisions and can have severe side effects.
What we need is a way to find out which formulas to update when any data changes or grows. Excel has provided this facility since 25 years. Unfortunately, very few people are even aware of it – leave alone using it!
