I have a data step thst gives me count
Of row per my grouping

Here it is
Data dep5;
Set dep5;
Count +1;
By top;
If first.top then count =1;
Run;
It works but it starts with the earliest date as 1 and most current with 5 I would need it to be the opposite of that for example

Top. Date. Count. Need to look
1. 02/01/2018. 1. 3
2. 02/05/2018. 2. 2
3. 03/01/2018. 3. 1

First you sort your data by descending and count the records by id and then sort back to ascending.

data have;                                                                                                                              
format date date9.;

Thanks for response SuryaKiran 
I'm still getting the number sequence from the earliest being one and latest with 20 since that number can fluctuate

Proper sort order will solve your problem. Please provide with some actual sample data with few records.

could you please try this code, it is the same I provided earlier 

 

not sure if you tried earlier but if you could try it will help you
