Import files from folder and filter between consecutive dates in query editor.

Hi Power BI User;

 

I'm facing with a filter challenge. I'm updating data from a folder, in this folder there are two files (File 1 and File 2).  The two files have a date column, I would like to filter from the second file (file 2) only the consecutive date from file 1. It is possibile implementing this filter in the query editor?

 

Thank you in advance.

    You want an Anti-Merge. Starting with table 2, merge the date column with the date column of Table 1, but select Left-Anti-Join.

    It will return a table like this. This shows I've already deleted the merge column. There is no need to expand it as I only wanted to limit the rows of table 2, not actually bring in additional info from table 1.

     

    See this Power BI file to see the full M code.

    If your dates get wonky, change the Localization steps. I used Bahamas so your DD/MM/YYYY would work on my US region computer.

    Not sure I understand this, sample data would help tremendously. ImkeF and edhans may be able to pull off some magic.

      I would like to find a method in the query editor (if possibile) to filter from the FILE 2 only the consecutive date from file 1 and excluding from the file 2 the date that are present in the file 1.

        Anonymous ,

         

        It seems the dates which have been marked as green are not consecutive date. Could you please clarify more details about the logic of your requirement?

         

        Regards,
