Hi Experts,

I need to generate unique number as per the following format...

This Unique Number comprises of 4 sections.
Suppose, Number is "E17100007" (which is unique)

1. E is first character from Column B
2. 17 is 2 digit Year from Date Column (C)
3. 10 is 2 digit Month from Date Column (C)
4. 0007 is four digit number which will grow by 1 within its group. (Consider that this number does not exceed 9999 limit)

Where group is 'E1710' and number will be get incremented but if group changes then it will start from 0001.

When I use this formula it reset all the numbers falls after it.

It should not be actually.

It should first find out the maximum and and then increment. All the previously generated numbers should intact.

How to achieve the task? (If it is VBA than it will be better)

Sample file is attached?
