Solved: Re: How to select dataflow based on variable?

SjoerdV · ‎09-26-2019

Hi all,

I'm developing a model that get's it input via Dataflows. However, since we want to look at numbers as they were on a cut-off date and with the latest figures available, I'm trying to switch between Dataflows via a parameter. This is where I'm affraid I need a bit of help.

So I've got 2 Dataflows (A and B) that are added in Power Query, I also have a parameter with text-values A or B.

To start, I reference in my fact_query the source-step as follows; = Table.SelectColumns(A,{"colums"}). As A is the table to reference, I tried various options of "&parameter&". This works, but it would only see a single-column that consists of A. So how can I tell Power Query I expect it to look into Dataflow A?

Can you guys help me with what I'm missing here?

Many thanks in advance.

Many thanks @v-juanli-msft !

In the end I created 2 versions of each dataflow (already had that of course), one named A LIVE and the other one A CUTOFF. Then I created a text-parameter with 2 options, LIVE and CUTOFF. After that it was simpy a matter of selecting the workspace the dataflows reside in, filtering on all dataflows that contain "A" and then filter on dataflows names that end on the parameter-value. From there on simply expanding etc etc.

In the end I think I was in the right direction, only wrong with the coding.

Nevertheless, thanks again!
