Supplier Master Data Cleanse, Standardization, and Accuracy

We are working on standardizing the supplier master data. Below are my initial considerations to start identifying the suppliers that can be inactivated.

Initial Considerations:

1.⁠ ⁠Suppliers with no active sites.

2.⁠ ⁠Suppliers with no transactions (AP Checks, AP Payments, POs, Requisitions) within the last 5 years.

3.⁠ ⁠Duplicate suppliers (with similar names).

Have you anyone undertaken a similar project? Share your experiences.

⁠⁠What additional criteria did you consider?

⁠⁠How did you handle exceptions or disputes?

Your inputs will be highly appreciate.
