Flagging Duplicates based on Multiple conditions

Dear Forum,

Flagging Duplicates based on Multiple conditions..

I have attached the file for reference with Dummy Data as the actual data runs in thousands...

What I require is to flag Duplicates with some formula so that I can filter and then later delete those specific rows from the records...

The Duplications has to be considered on Multiple criterions:
1. If the FNAme and LName is appearing for one Company more than once.

2. Sometimes there would be inconsistency in Data Entry, so the FNAme would be typed in the Column for LName and vice-versa.The code needs to understand the same.

3. Alongwith the above, if the Designation is different then the record with the Lower Designation based on the Weightage should be Flagged as "Duplicate".
Ex: -

4. If there's a tie between the same designation then the record with the Maximum information across all the columns having Max info should be Unique.
Ex:- The amount of details mentioned in the following columns would determine the record to be termed as Duplicate or unique

5. If still the records are identical then the first occurence can be unique...

I have made this data to give an example as the actual data is very confidential.

Please allow room for adding New Designations as the Designation and their Weightage needs to be Dynamic.

Please refere the Word doc Duplication Criterion Explanation for the explanation.
