transition matrix of my data %0D%0A

Hello I have data like this:

Large Corporate - CCAR Scenario
Q2-2020 data	q1	q2	q3
I-1	1	2	3
I-2	4	5	6
I-3	7	8	9
US Commercial - CCAR Scenario
Q2-2020 data	q1	q2	q3
I-1	1	2	3
I-2	4	5	6
I-3	7	8	9

And I want to change my table like this:

Sector	FROM_RISK_RATING	scenario_date	MIGRATION_PROB_D
Corporate	I-1	Q2-2020	1
Corporate	I-2	Q2-2020	2
Corporate	I-3	Q2-2020	3
Corporate	I-1	Q2-2020	4
Corporate	I-2	Q2-2020	5
Corporate	I-3	Q2-2020	6
Corporate	I-1	Q2-2020	7
Corporate	I-2	Q2-2020	8
Corporate	I-3	Q2-2020	9
Commercial	I-1	Q2-2020	1
Commercial	I-2	Q2-2020	2
Commercial	I-3	Q2-2020	3
Commercial	I-1	Q2-2020	4
Commercial	I-2	Q2-2020	5
Commercial	I-3	Q2-2020	6
Commercial	I-1	Q2-2020	7
Commercial	I-2	Q2-2020	8
Commercial	I-3	Q2-2020	9

How can I change the format in SAS? Thanks!

Instructions here: https://communities.sas.com/t5/SAS-Communities-Library/How-to-create-a-data-step-version-of-your-data-AKA-generate/ta-p/258712 will show how to turn an existing SAS data set into data step code that can be pasted into a forum code box using the </> icon or attached as text to show exactly what you have and that we can test code against.

however, my original data is larger than this, so I need to transpose the original data

I've attached a file for further explanation. So the original file is in excel and I want to import it into SAS and make the format as the desired tab.

Many users here don't want to download Excel files because of virus potential, others have such things blocked by security software. Also if you give us Excel we have to create a SAS data set and due to the non-existent constraints on Excel data cells the result we end up with may not have variables of the same type (numeric or character) and even values.

Subset your data an use the macro to create an example data set using the link I posted earlier.
