Line Item Number or Bill Number in Cash Account and sales invoice

There is any possible option can add line item or bill number in sales invoices or in cash account while preparation? Because when we are entering different bills in daily cash account (i.e… provision purchase, meat purchase, vegetables, fruits, egg …) Is it possible?

your question is not clear.
if you are asking about having line numbers for each row, read this guide Manager Cloud

If we are preparing daily cash book accounts, there is lot of daily purchase bill entries, each entries have bill numbers. We have only 1 bill number or invoice number each cash account but we have lot of entries for each items i.e provision purchase Bill, beef purchase bill, Fish purchase bill etc. these each bill have numbers (i.e 1001, 2010, 3254 etc). So how can we enter these numbers in entries.

You could put the bill numbers into the Description field for each item entry.
