Hierarcal Problem with two columns to determine Top level

[maqsud]

Given:

I have Two columns as shown below as shown below

Employee ID	Manager ID
E068	E067
E071	E067
E229	E069
E248	E144
E226	E223
E236	E241
E066	E001
E067	E001
E144	E001
E223	E001
E069	E066

Problem Statement:

This problem is to identify the Head of Manager by using Employee and their Manager data.

About:

We have an Employee ID and their Manager ID. Please note that Manager ID are from Employee ID. Since each manager has one Manager above their level.

STEPS:

1. First, we'll take all UNIQUE ID in Manager ID column.
2. Then for each ID from Manager ID column, we will look for their respective Manager ID(Manager)
3. Then we will create a new column say `Level 1` we will put manager for each Manager ID on their respective cell.
4. Similarly, we will repeat the above 3 processes again till there is no Manager ID for that particular ID.
5. This way we can identify the Head of Manager.

I am able to solve the problem in EXCEL.
By using =IFERROR(VLOOKUP(C2,$A:$B,2,FALSE),"")

But this approach lead me to create new column in excel for each level hierarchy. And putting the formula on first cell of that particular column and then dragging the result for each manager

But incase of big companies there would be **n** no. of level of hierarchy. So creating the new column in excel for each level of hierarchy would be time consuming task. Hence, I am looking for an optimal solution.

Expected Output:

Employee ID	Manager ID	Level 1	Level 2	Head of Manager
E068	E067	E001		E001
E071	E067	E001		E001
E229	E069	E066	E001	E001
E248	E144	E001		E001
E226	E223	E001		E001
E236	E241			E241
E066	E001			E001
E067	E001			E001
E144	E001			E001
E223	E001			E001
E069	E066			E001

The Employee ID column contain **UNIQUE ID** while Manager ID contain **DUPLICATES ID**.

Thank you for your time and consideration.

Hi @maqsud ，

Create 4 calculated columns as below:

Column = 
var _employee=CALCULATE(MAX('Table'[Manager ID]),FILTER('Table','Table'[Employee ID]=EARLIER('Table'[Employee ID])))
Return
CALCULATE(MAX('Table'[Manager ID]),FILTER('Table','Table'[Employee ID]=_employee))

Level 1 = 

IF('Table'[Manager ID] in FILTERS('Table'[Column]),BLANK(),'Table'[Column])

Level 2 = 
var _managerID= CALCULATE(MAX('Table'[Manager ID]),FILTER('Table','Table'[Column]<>BLANK()&&'Table'[Level 1]=BLANK()))
var _column=CALCULATE(MAX('Table'[Column]),FILTER('Table','Table'[Column]<>BLANK()&&'Table'[Level 1]=BLANK()))
Return
IF('Table'[Level 1]=_managerID,_column,BLANK())

Head of Manager = IF('Table'[Level 2]<>BLANK(),'Table'[Level 2],IF('Table'[Level 2]=BLANK()&&'Table'[Level 1]<>BLANK(),'Table'[Level 1],IF('Table'[Level 2]=BLANK()&&'Table'[Level 1]=BLANK(),IF('Table'[Column]<>BLANK(),'Table'[Column],'Table'[Manager ID]))))
