NEWBIE HELP POWER BI

Hello,

 

I'm really new in using PowerBI and I'm just trying to study functions and create reports of future implementation.

 

Some background:

The data I have is already around 500,000 rows. My month column is formatted as YYYY/MM and read as MM/DD/YYYY by PowerBI. All the DDs are 1 since there are no dates. Weeks are formatted as YYYY/WW, but read as WW/DD/YYYY.

 

I tried using delimeter to create a separate week and month column through query. If I'm not mistaken, I read that I have to duplicate of my current master query and manipulate from there. After creating the three new columns, I removed other columns for easier loading. I don't know if this is right.

 

After trying to apply, I get this error on the values of my Week column although its format is already a whole number 

"DataFormat.Error: We couldn't parse the input provided as a Date value.
Details:
2015/13" 

 

Also, another thing: PowerBI adds a row number column automatically with weird numbers. Is that normal? Do I delete it? Is it related to the indexing, something I read online as well? Thank you guys so much in advance.

Hope you guys can help. I have so much questions and I hope this website can guide me through.

What I think you might need is a date table, which you can then use those columns when joining on a date table?

Here is a link to a great blog post which explains this: http://radacad.com/do-you-need-a-date-dimension

well as far as i can tell this is your problem 2015/13 is not a whole number, a whole number would be 201513 so it looks like it is failing, you will have to clean those values up.





If I took the time to answer your question and I came up with a solution, please mark my post as a solution and /or give kudos freely for the effort 🙂 Thank you!

Do you have any suggestion on how to clean the values? It's filtered so I expect the 2015/13 to appear via filter, but all I can see are 1,2,3,...12,...,53, which represent the weeks of the year. I tried searching/expanding the filter list but it says it can't parse the data. Any suggestions on how to do this? Thank you.
