Hello Everyone,
I have a file "reference" that only has unique data and takes data from another file "input".
But "reference" file should always contain up to date information.
And I only need to update, for example, ID-2090's rate and bill while leaving the data in other columns untouched.
While "reference" file might contain only 7 columns, "input" file contains 30/40 columns.
So I need to update the Pace and Measure for a person when:
1. They are available in both files.
2. They are only available in "reference" file - then keep all the data as is.
3. They are only available in "input" file, then add their data to the "reference" file.
| Unique ID | Name | Pace | Measure | Column A | Column B | Column C |
| 1012 | ABC | 200 | 650 | Data | Data | Data |
| 2012 | DEF | 300 | 750 | Data | Data | Data |
| 2090 | EFG | 400 | 850 | Data | Data | Data |
| 2098 | XYZ | 500 | 950 | Data | Data | Data |
| 2080 | BNC | 600 | 1500 | Data | Data | Data |
| 1080 | NBC | 350 | 800 | Data | Data | Data |
The problem I am facing is that I am not able to update only the Pace and Measure of an ID available in both files while keeping the rest of the data constant. Primary key here would be the ID which is unique.
Any help is much appreciated. Thanks!
