We manage our stocks in Excel. I know him a little old-fashioned, but we are developing a business firm, and we have all our money blocked in business, and there is no money for investment in IT.
So, I wanted to know if I can program in such a way that excel automatically complements product numbers?
This is an example of one product category.

All of our design codes are 6 digits. I really want that when adding only a partial number and clicking on it, it automatically completes the remaining digits, taking the above numbers.
So, for example, in this case, I expect that if I type 5hit enter, it will automatically make it 790705based on the number above.
