Dear Experts,
I have a scenario to compare two columns in two SharePoint lists (List A and B) as per below.

- If any of the values in List A (column Invoice) are found in List B (column invoice), update the corresponding Status field of List B to "Critical" else leave as "Normal"
- The Invoice columns can also be Null (Empty), so the flow should ignore empty from List A when comparing and keep Status in List B as Normal
- The values in Invoice are separated by a comma and can be in any order.
- I want to update List B everytime an item is created in List A.
Please I need your help on the flow steps/logic and diagram.
Regards,
Sam
