DAX Calculations
Hi, I have some data which is downloaded daily from our invoice system. We are looking to create a dashboard which will show the date that the invoices should be processed on to check work is being completed within Service Level Agreement. We work across global markets and some of these have different SLA dates to others. For example we have US policy which has a 4 day SLA from the created date and UK policy which has a 5 day SLA from created date. we have all the information from the download other than the SLA date and I am looking to insert a function to calculate the date automatically. All of the data for each policy is stored within the same excel download.

RE: DAX Calculations
Hi Lesley,
Thank you for the forum question.
I would do this with a Switch function in a column calculation.
SLA Date=Switch([Country],"USA",[Date]+4,"UK",[Date]+5,"DE",[Date]+7,............)
You will of course have to replace the names in the square brackets to you column names.
Kind regards

RE: DAX Calculations
Hi Lesley,
Your dates are not the data type dates. I guess that your dates are text strings and that's why you get the error. Change the data type in the query editor. If the query editor cannot do it (it may not recognise the data) please copy one of the "dates" and post it here.
Kind regards
