Data transformation Question

Dev_

I am working on a report where the data looks like below (sample data):

Services : JAS, GAF and YAG fall under the profit center "ABC" and HIG and OPD falls under "XYZ"

Date	Profit Center	Service
1/1/24	ABC
1/1/24		JAS
1/1/24		GAF
1/1/24		YAG
1/1/24	XYZ
1/1/24		HIG
1/1/24		OPD

I want my final output to look like below, there should be a profit center for each service in each row.

Date	Profit Center	Service
1/1/24	ABC	XCS
1/1/24	ABC	JAS
1/1/24	ABC	GAF
1/1/24	ABC	YAG
1/1/24	XYZ	HIG
1/1/24	XYZ	OPD

Can someone please guide me how can we do that in domo etl ? I know that window functions (lag,lead) aren't supported in Domo's mysql, so trying to find a solution with magic etl.

Thankyou

I think you want to fill down the Profit Center column, and once you've created a filled down Profit Center column, you could filter out the blank Service rows.

Here's a good explanation from @MichelleH on filling down using Group-By and Coalesce in MagicETL:

I also like the Python implementation from @user01506 (except that Python in a MagicETL feels like putting on a lobster bib at a Denny's)

Do the services map to profit centers? For example, is XCS always in the ABC profit center? How many total services & profit centers are there? Are there any other fields that group profit centers together?

@SS1108 If the service centers always map to the same profit center you could use a mapping table that joins into the ETL or you can do a beastmode/formula tile like below

case

when 'service' in ('XCS', 'JAS', 'GAF', 'YAG') then 'ABC'

when 'service' in ('HIG','OPD') then 'XYZ'

end

@DavidChurchman the explanation from @MichelleH was really helpful. I was able to successfully map the data. Thank you so much
