Hey Shin thanks for your response.
I have updated the tableau doc.
The allowed amount, total cost,savings and networks are all obtained directly from the database for both pre and post migration.
What i want to show is For each customer id what was the change if any between the sheet for Pre migration and pole st migration?
Like if one customer id got had 1000 total cost with 500 allowed and savings of 500 pre-migration
and if the same customer id got 1000 total cost with 400 allowed and savings of 600 post migration.
How do I show this comparison for many customer id's?
That was really helpful. Is there a way I can get a count of the Delta for each individual value?
Like how many had a delta of savings as zero?
