I used Power BI Desktop, and I just starting to use this tool around a week ago. I am fully newbie. I created the visualization based on some measures based on my Excel workbook, "Critical material for PBI.xlsx". It was incredible, and very exciting, my boss is very happy with the visualization that I'am present in the meeting on the day 1, which is this morning. But then, the data source is updated, since we close some issues on some records.
The meeting is on daily basis, which is tomorrow morning, but I still don't know how to update my dashboard (visualization), no changing column header, no column inserting in my Excel workbook. Just update in some cells.
Is there someone could help and assist me on this subject, please? Really appreciate in advance for your help and assistance.
