Checking Data Completeness

Anonymous — Wed, 07 Oct 2020 20:09:10 GMT

Hi I am new to PowerBI/PowerQuery, the following task might be trivial to some of you, but your help is highly appreciated 😁.

For example:

I have three columns, where each column is presented from different files

Vendor Name	Masterfile A	Masterfile B	Status
A	xxx	xxx	Complete
B		xxx	Incomplete
C			Incomplete

I want to develop a new column called "Status" where it will examine the completeness of column Masterfile A and Masterfile B.

When BOTH columns were filled it will say "Complete" as in Vendor A
When ONE column or BOTH are NOT filled it will say Ïncomplete" as in Vendor B or C

I think the best approach to this is using the Switch True function of If function. I might be wrong.

Regards

you can decide where to implement that check, in Power Query or in Power BI/DAX. Since the data is not impacted by user filters this means in DAX you would use a Calculated Column (not a measure)

The syntax is slightly different.

Power Query:

newstep = Table.AddColumn(previousstep,"Status", each if #"Masterfile A" = null or #"Masterfile B" = null then "Incomplete" else "Complete")

DAX:

Status = IF([Masterfile A]==BLANK() || [Masterfile B] == BLANK(),"Incomplete","Complete")
