Parent/Child Hierarchy with duplicates in Employee ID

[phaneendra]

Hi everyone,

This is my first post in the community and i am super excited.

I have a data table as follows

Employee_ID	Manager_ID
1
2	1
3	2
4	3
5	4
6	5
7	6
8	7
9	8
10	9
9	1
10	2

There are cases where some employees has more than 1 reporting manager. For instance Employee 9 reports to two managers 1 & 8. Likewise, Employee 10 has reports to managers 9 & 2.

This is my output when there are no duplicates in the employee ID`s

But, because of duplicate employee ID`s, this is the error I face

Please help me in resolving this error with the data sample data set i`ve shown above.

Really appreaciate Your support! 

Thanks in advance!!

Hi,

You should be able to add a first column of this kind : 

Employee_UMID =

var employeeID = Employees[Employee_ID]

var managerID = Employees[Manager_ID]

var sameEmployeeID = SUMMARIZE(FILTER(Employees,Employees[Employee_ID]=employeeID),Employees[Employee_ID],Employees[Manager_ID])

var rk = RANKX(sameEmployeeID,[Manager_ID],managerID,ASC,Dense)

return employeeID & if(rk>1, "_" & rk,"")

As it's returning a text, you need to change Manager_ID as text column (or apply a number you are sure will not be duplicate instead),

then you should be able to apply your path : 

Column =

var p = PATH(Employees[Employee_UMID],Employees[Manager_ID])

var m = SEARCH("_",p,1,LEN(p)+1)

var r = LEFT(p,m-1)

return r

From whether technique or business perspective, it's bizarre that one employee is situated at different levels of the same organizational hierarchy. If he/she indeed plays different roles, assign different IDs to him/her. Or, a straightforward solution is to create another funcitonal hierarchy.

Hi,

Thanks for taking time to investigate!

Let me explain the scenario. An employee was reporting to manager-A, Later in that month for some reasons the employee starts reporting to Manager-B. The system is taking time to update, so at times we get duplicate records. In such cases I face this issue in DAX.

Hope this brings in more light!!

As to me, tt's kind of "slowly changing dimension" case.

Like I said, assign different to the employee and add different records in the Employee dimension table accordingly.

There are certain instrinsic constaints. Your case is inherently restricted. Refer to the official document,

PATH function (DAX) - DAX | Microsoft Docs

“

• If ID_columnName has duplicates and parent_columnName is the same for those duplicates then PATH() returns the common parent_columnName value; however, if parent_columnName value is different for those duplicates then PATH() returns an error. In other words, if you have two listings for the same employee ID and they have the same manager ID, the PATH function returns the ID for that manager. However, if there are two identical employee IDs that have different manager IDs, the PATH function returns an error.

Hi,

Thank you for your inputs. Yes you are right. But, our system doesnt permit us to alter the employee ID. 

However, I was able to find a solution using M-Query which resolved the issue. I am trying to replicate the same in DAX without using PATH function. Since, PATH function doesnt accept duplicates in Employee_ID.

Thanks for your time!!
