Date Time Circular Dependency


I'm having trouble with A date table to plot two values on the same line graph with date as the x axis.  I've tried a date table and hour table as well but above is the simplest represenation.  My "New Well Forecast" table only has one value per date while the "Production" table has a value for every hour of every day.  When I plot this chart with the relationships above, it only shows the Date/Times that are in the "New Well Forecast Table" and shows no values from the production table.  


I've tried a number of different solutions.  The new well forecast table should really be merged with the production table but the production table is a direct import.  I can't do it in SQL either.  Can anyone help me out?

Hi @bojangles35 ,


The relationship of your model is wrong,please try what said before, then try to create a measure to calculate the two values you want

@bojangles35 , In this case, your Date needs to be date-time table.

Then you can join it with production and datetime and with forecast  on Date (Many to Many) , but that should work fine.

If needed, you can separate date table too, which join with date from both tables. In case of Production you have create a date without timestamp to join



Date = [datetime].date
Date = date(year([datetime]),month([datetime]),day([datetime]))

in Power Query

Hi amitchandak,


Thanks for the help and sorry for the late reply.  I am linking both tables to the Date Table with Date/Time and have all hours of the day for the Date table and production table but only one hour for the Forecast table.  I wrote my question quickly so missed some things.  I need to filter everything by "Well".  This is the unique identifier in the "Well" Table but is in all three tables and the connection between all of them.  .  



The filtering seems to acutally be the issue.  I have a slicer for "Well" from the New Forecast Table.  When the relationship between the Well table and New Well Forecast table is both directions as in my original post, I only get the "Date/Time" that's in the New Well Forecast Table for the "Gas Actuals" from the production table.  It should have all hours of the day.  


If I have the relationship as single directional filter as below, the Date/Time aspect works but the "Well" Slicer doesn't do anything, all wells are always selected.  (You can see this in the 12/2 12:00 AM as the previous 5853 doesn't match below because there are two "Wells" even though the slicer has one).
