- how to find duplicates in the FoodChain-Lab database
- how to remove these duplicates
Note: You need data from the tutorials “Data collection and import” and “Tracing backward template”. Please do these tutorials first.
1
- Open the database and import “FCL_Backtrace_Start_tob_en_FDF_DB_clean.xlsx”.
2
- Have a look at the network in the Tracing View. There is station Dry Stuff Inc and another one called Dry Stuff Incs. In the network it looks as if the the refined sugar was delivered to the Finest Dough Factory by a completely different supplier. Because in reality both stations are identical this typo should be corrected.
3
- Start the similarity search (see button in the red circle).
4
- To search for duplicates in station names and addresses tick the encircled radio button.
- “Name: 90” means that the similarity between two or more station names must be 90 % or greater in order to be displayed as duplicate.
- Click “OK”
5
- Left click the row with the typo to highlight it. Then drag and drop it onto the row that should be kept. It is like moving a file (or a selection of files) to a folder in a file browser.
- Click “OK”.
- Because there are no more station names with 90 % similarity the window closes.
6
- Reset the Supply Chain Reader and have a look at the Tracing View.
- The entries have been merged. The refined sugar has been assigned to the correctly spelled company station Dry Stuff Inc.
