Unrelated Tables

Hi. I've tables that are not related as you can see in the picture below (no unique values in either one to create relationship). But, I need to pick a row from ItemTransaction table and check upon B...

The tables' sample is attached here. Both will return multiple rows when we filter by ScheduleID. Any suggestions on how to loop through row by row?

Hi tracy,

 

You can refer to below measure to calculate the total seconds:

 

subtotal =
SUMX(FILTER(ALL(ItemTransaction),ItemTransaction[ScheduleID]=MAX(BreakTime[ScheduleID])&&AND(MAX(BreakTime[BreakStartTime])<=ItemTransaction[StartTime],MAX(BreakTime[BreakEndTime])>=ItemTransaction[EndTime])),ItemTransaction[BundleTime])

 

Tables:
Breaktime.


 

ItemTransaction.


 

Result(add a calculate column to display the result):


 

Notice: Since the sample data has no match records, I modified some records.

    Hi Anonymous. Thanks for your reply. You have used MAX ItemTransaction[ScheduleID] = MAX(BreakTime[ScheduleID]) in this statement. Does that mean it will always pick the first row? Because somehow scheduleID will be the same for the selected rows in BreakTime table. 

    Sorry, I don't quite understand what your expression does. Do you mind explaining?

    I gave a sample condition only. But, in actual I've 4 conditions. Can I fit in them in the same measure?

     

    //If BreakTime is out of TrxTime, No BreakTime
if (vBreakTimeEnd <= pStartTime) { break; } 
if (vBreakTimeStart >= pEndTime) { break; }

//If TrxTime is between BreakTime
if (vBreakTimeStart <= pStartTime && vBreakTimeEnd >= pEndTime) 
   vTotalBreakTime += (pEndTime - pStartTime).TotalSeconds;
//if BreakTime is between TrxTime
else if (vBreakTimeStart >= pStartTime && vBreakTimeEnd <= pEndTime)
   vTotalBreakTime += (vBreakTimeEnd - vBreakTimeStart).TotalSeconds;
//if BreakTime starts before TrxTime
else if (vBreakTimeStart <= pStartTime && (vBreakTimeEnd >= pStartTime && vBreakTimeEnd <= pEndTime))
   vTotalBreakTime += (vBreakTimeEnd - pStartTime).TotalSeconds;
//if BreakTime starts after TrxStartTime
else if (vBreakTimeEnd >= pEndTime && (vBreakTimeStart >= pStartTime && vBreakTimeStart <= pEndTime))
   vTotalBreakTime += (pEndTime - vBreakTimeStart).TotalSeconds;

      Hi tracy,

       

      >>You have used MAX ItemTransaction[ScheduleID] = MAX(BreakTime[ScheduleID]) in this statement. Does that mean it will always pick the first row?


      It will get the current “scheduleID”, for more detail information about measure and calculate column, you can refer to below link:
      column vs measure

       

      According to your conditions, you want to get the “middle range” of tables and get the total minute of these records, right?

       

      You can try to use below formula to see if it works on your side.

      Measure:

      condition total = 
var currBreakStart=MAX(BreakTime[BreakStartTime])
var currBreakEnd=MAX(BreakTime[BreakEndTime])
var currScheduleID=LASTNONBLANK(BreakTime[ScheduleID],BreakTime[ScheduleID])
return
SUMX(FILTER(ALL(ItemTransaction),
ItemTransaction[ScheduleID]=currScheduleID&&AND(ItemTransaction[StartTime]<currBreakEnd,ItemTransaction[EndTime]>currBreakStart)),
DATEDIFF(MAX(ItemTransaction[StartTime],currBreakStart),MIN(ItemTransaction[EndTime],currBreakEnd),SECOND))

       

       

      If above is not help, please feel free to let me know.

        Hi Anonymous, I created a measure as you had given. But, the calculated column using your previous expression (TotalSecond = IF([Condition Total]=BLANK(),0,[Condition Total])) throws this error:
        A circular dependency was detected: BreakTime[Column], BreakTime[TotalSecond], BreakTime[Column]

         

        Also, I actually want to update the total seconds in ItemTransaction table like below. I want the calculated break time beside each employee's record. Is this possible? 
        ***Very importantly, can you advise me if we can put the other conditions in the same measure pleaseee?
