I have been tasked with creating Power BI KPI reports and the data to feed those reports comes from different sources and is collected manually.
There is one person responsible per KPI. That person collects the KPI's data monthly and puts it in an Excel file. Then, that person sends the xlsm file to another person, who is responsible of organizing multiple KPI's into one Excel file. Ultimately, that person sends it to me and I use that xlsm file to create the report. The same process goes on per area of the company (6 in total) every month.
As you can see, there is a lot of copy/paste going on which can indice errors.
What is the best way to approach this?
