Complex IF Statement

rebrow31 — Wed, 21 Jul 2021 11:50:09 GMT

I have a table with a machine column and a minutes column. There are 9 different machines and the table is recording the events in which a machine was stopped and how long it was stopped for (the minutes column).

Now, for just 4 different machines I need to return a value base on the minutes column. But the values returned depend on both the machine and the minutes. For example:

Machine 1 - If minutes between 0-3, I need to return 0. If minutes between 3-8, I need to return 1. If minutes between 8-13, I need to return 2. If minutes in between 13-18, I need to return 3. If minutes between 18-23, I need to return 4. If minutes between 23-28, I need to return 5. If minutes are above 28, I need to return 6.

Machine 2 - If minutes between 0-2, return 0. If minutes between 2-7, return 1. If minutes between 7-12, return 2. If minutes between 12-17, return 3. If minutes between 17-22, return 4. If minutes between 22-27, return 5. If minutes are above 27 minutes, I need to return 6.

Machine 3 - If minutes between 0-3, return 0. If minutes between 3-8, return 1. If minutes between 8-13, return 2. If minutes between 13-18, return 3. If minutes between 18-23, return 4. If minutes between 23-28. return 5. If minutes above 28 minues, rturn 6.

Machine 4 - If minutes between 0-2, return 0. If minutes between 2-7, return 1. If minutes between 7-12, return 2. If minutes between 12-17, return 3. If minutes between 17-22, return 4, If minutes between 22-27 return 5. If minutes above 27 minutes retun 6.

There are 9 machines, so the additonal 5 machines I just want all the display 0.

Does anyone know how I write this?

We still don't know if you need a measure or a calculated column...

Well that is because I do not know. I am not good on Power BI with this type of thing, which is why I am asking for some help. Maybe you could suggest which should be better?

I've managed to come up with this which works fine:

Shots = IF (Downtime[Machine] = "DCM01", IF(Downtime[Downtime] < 120, "0", IF(Downtime[Downtime] < 240, "1", IF(Downtime[Downtime] < 360, "2", IF(Downtime[Downtime] < 480, "3", IF(Downtime[Downtime] < 600, "4", IF(Downtime[Downtime] < 720, "5", IF(Downtime[Downtime] < 840, "6", IF(Downtime[Downtime] < 960, "7", IF(Downtime[Downtime] < 27000, "8"))))))))), IF(Downtime[Machine] = "DCM02", IF(Downtime[Downtime] < 300, "0", IF(Downtime[Downtime] < 600, "1", IF(Downtime[Downtime] < 900, "2", IF (Downtime[Downtime] < 1200, "3", IF (Downtime[Downtime] < 1500, "4", IF (Downtime[Downtime] < 1800, "5", IF (Downtime[Downtime] < 27000, "6")))))))))

However I need to insert 2 more machines in there and it isn't letting me do this because IF function can only have 3 arguments. Which I get but how do I go round being able to put additional rules in for 2 more machines?

Hi rebrow31 ,
Make use of variables to do that:

Shots =
Var Machine 1= IF(Downtime[Downtime] < 120, "0", IF(Downtime[Downtime] < 240, "1", IF(Downtime[Downtime] < 360, "2", IF(Downtime[Downtime] < 480, "3", IF(Downtime[Downtime] < 600, "4", IF(Downtime[Downtime] < 720, "5", IF(Downtime[Downtime] < 840, "6", IF(Downtime[Downtime] < 960, "7", IF(Downtime[Downtime] < 27000, "8"))))))))), IF(Downtime[Machine] = "DCM02", IF(Downtime[Downtime] < 300, "0", IF(Downtime[Downtime] < 600, "1", IF(Downtime[Downtime] < 900, "2", IF (Downtime[Downtime] < 1200, "3", IF (Downtime[Downtime] < 1500, "4", IF (Downtime[Downtime] < 1800, "5", IF (Downtime[Downtime] < 27000, "6"))))))))

Var Machine 2= conditions for machine 2
Var Machine 3= conditions for machine 2

Return IF (Downtime[Machine] = "DCM01", Var Machine 1, IF (Downtime[Machine] = "DCM02",Var Machine 1,
IF (Downtime[Machine] = "DCM03", Var Machine 3)))

I hope this helps!

Your code is totally unmaintainable. By writing it like this you're shooting yourself in the foot. There is a much better way to write it.

If all you want is a calculated column, then you should do it the way I'm going to describe. You should create a MachineConfig table with the following columns:

Machine|LowerBound|UpperBound|Value
------------------------------------
Machine1|0|3|0
Machine1|3|8|1
...
Machine2|0|2|0
Machine2|2|7|1
...
This is what it should look like in a good professional model.

Once you've got this table, it's dead easy to add a column with the right Value's to your table T.

[Value] = /// calculated column in T var TheMachine = T[Machine] var TheMinutes = T[Minutes] var TheValue = MAXX( FILTER( // This filter should return just // one row if everything is correctly // coded. MachineConfig, MachineConfig[Machine] = TheMachine && // You should decide which bound // is inclusive and which is exclusive. Machine[LowerBound] <= TheMinutes && TheMinutes < Machine[UpperBound] ), MachineConfig[Value] ) return TheValue

The code will, of course, adjust itself automatically to the entries in the MachineConfig table.

Again, please do not write code like this as it's completely unmaintainable and plain ugly.

Thank you so much for your help. It makes sense, I had no idea about variables. I am still getting an error messgae though, could you shed any light on what might be wrong?:

Shots =

Var Machine 1= IF(Downtime[Downtime] < 2, "0", IF(Downtime[Downtime] < 4, "1", IF(Downtime[Downtime] < 6, "2", IF(Downtime[Downtime] < 8, "3", IF(Downtime[Downtime] < 10, "4", IF(Downtime[Downtime] < 12, "5", IF(Downtime[Downtime] < 14, "6", IF(Downtime[Downtime] < 16, "7", IF(Downtime[Downtime] < 450, "8")))))))))

Var Machine 2= IF(Downtime[Downtime] < 5, "0", IF(Downtime[Downtime] < 10, "1", IF(Downtime[Downtime] < 15, "2", IF (Downtime[Downtime] < 20, "3", IF (Downtime[Downtime] < 25, "4", IF (Downtime[Downtime] < 30, "5", IF (Downtime[Downtime] < 450, "6")))))))

Var Machine 3= IF(Downtime[Downtime] < 3, "0", IF(Downtime[Downtime] < 8, "1", IF(Downtime[Downtime] < 13, "2", IF (Downtime[Downtime] < 18, "3", IF(Downtime[Downtime] < 23, "4", IF(Downtime[Downtime] < 28, "5", IF(Downtime[Downtime] < 450, "6")))))))

Var Machine 9= IF(Downtime[Downtime] < 2, "0", IF(Downtime[Downtime] < 7, "1", IF(Downtime[Downtime] < 12, "2", IF(Downtime[Downtime] < 17, "3", IF(Downtime[Downtime] < 22, "4", IF(Downtime[Downtime] < 27, "5", IF(Downtime[Downtime] < 450, "6")))))))

Return IF (Downtime[Machine] = "DCM01", Var Machine 1, IF (Downtime[Machine] = "DCM02", Var Machine 2, IF (Downtime[Machine] = "DCM03", Var Machine 3, IF (Downtime[Machine] = "DCM09", Var Machine 9))))

rebrow31 , The variable names could be a problem...should be a single string. My bad.
Machine_1, Machine_2.

Also, give a try for Anonymous 's solution.
