COPY DATA FROM PREVIOUS ROW TO POPULATE MISSING DATA BETWEEN DATES

[habaholic]

I have a file, "Production"that shows date, machine and mold for ONLY the day production started.

I have another file, "Downtime" that shows date, machine, downtime reasons for EVERY day.

I want to link the 2 tables so I can show which mold (Production) was on which machine for any downtime reason (Downtime).

I have merged columns machine/date in both tables and used this column to link the tables. But in my visuals, I only see the mold data for the dates where production started.

I want to modify my "Production" file to show machine and mold for all days. So if the file shows for example:

Date                                  Machine                        Mold

02/03/2017                       JW1201                        332.030.2

06/03/2017                       JW1201                        650.545.1

I want to populate the days in between with the data from the previous row. For 03, 04, and 05/03/2017 the same mold was on the machine as was on it on 02/03/2017).

I have 45 different machines so I should end up with a file that has 16425 rows for 2017.

Suggestions?

@habaholic,

1. Create a date table in Power BI Desktop.
2. Add two columns in Production table to calculate min date and max date for each machine.
3. Merge date table and Production table, use Fill down feature to fill some columns and create some required custom columns. For more details, please review the following PBIX file.
