DataFormat.Error: We couldn't parse the input provided as a DateTime value.

Hi there!

 

I am having following problem when I bring data from PBI dataflows:

 

1. I've created a dataflow and a linked table inside from an existing dataflow which have some date columns (format mm/dd/yyyy). This is my bronze layer with raw data:

 

 

2. When a create my silver layer dataflow to transform the data, I create a linked table to my bronce dataflow. The linked table should be the same since I've not transform the data yet, but see the following snapshot:

 

 

It seems the format is modified to dd/mm/yyyy and throws an error it cannot be parsed. I've tried change the data type using locale but not working. Any thoughts?

 

Thanks

    Hi Anonymous 

    The date format for your original is “mm/dd/yyyy” and everything seems normal . When you create a linked table to your bronce dataflow , the date format appears to be converted to “dd/mm/yyyy” , but in fact it is still "mm/dd/yyyy" , in the case where the day and month positions are converted, but the format is not converted, once the number of day is greater than 12, an error will occur, because there are only 12 months in a year.


    You can use Replace value in Power Query Editor to change the day and month positions and then change the date format .

    I had something very similar with a Date Lookup I had set up in a dataflow in one workspace.

    In another workspace I'd created another dataflow and then linked to the Date Lookup entity from there. When I created a report, a lot of the dates were showing as <error> where the dates were obviously trying to convert English dates to American format and failing. 

    It took me a little while to realise that the source dataflow was set to English (United Kingdom) and the target was English (United States). I changed it in Options | Project Options and was fine then.
