How to do a vlookup between two excel and remove duplicates in Power BI

[cesarfg1991]

I have 2 excel files ("task_sla", "sn_sm_finance_request") with matching columns (same values) in the column "NUMBER" for "sn_sm_finance_request" and "TASK" in "task_sla".

In Excel I used VLOOKUP doing a crossover comparing "NUMBER" in "task_sla" (in the field "TASK") and comparing "TASK" in "sn_sm_finance_request" (in the field "NUMBER" and then remove some duplicated values to match both Excel files.

I'm starting to work with Power BI and I want to know if there's a way to apply this (with formulas, don't know, I'm a newbie) to automate this process I do in Excel into Power BI.

Is there's a way. How formulas, which Power BI processes should I look? Maybe como bibl

Hope you can support

Hi @cesarfg1991

You can use the DAX function LOOKUPVALUE(). 

It returns the value for the row that meets all criteria specified by one or more search conditions.

Syntax:

LOOKUPVALUE( <result_columnName>, <search_columnName>, <search_value> [, <search2_columnName>, <search2_value>]… [, <alternateResult>] )

For more details, please refer to: LOOKUPVALUE function (DAX) - DAX | Microsoft Learn
