Results

Branch	Sale_Date	br_cnt	Return_Date	ret_cnt
Western	06-2019	11
Eastern	06-2019	5
Central	06-2019	2
Western	07-2019	1
Central	08-2019	1
			06-2019	11
			07-2019	5
			07-2019	2
			08-2019	1
			08-2019	1

Desired result is a proc report as follows:

Branch	06-2019	07-2019	08-2019	Row Total
Central	2	0	1	3
Eastern	5	0	0	5
Western	11	1	0	12
Total Branch	18	1	1	20
Total Return	11	7	2	20
Return Rate	163.64%	14.29%	50.00%	100.00%

Return rate is total branch/total return

Hi:
I'm not sure I completely understand what it is you need to do. Your data and your desired report don't make sense to me. You don't need as many datasets as you show to deal with SET1 and it's not clear to me about the extra rows you've added. Here's an example of the main report:

For some insight into COMPUTE blocks and adding extra rows (such as you show with your calculated percent), please refer to this paper https://support.sas.com/resources/papers/proceedings17/SAS0431-2017.pdf .
