Hi All,
I have a virtual table
_Table = GENERATE(
SUMMARIZECOLUMNS(ActivitySheet[StartTime2], ActivitySheet[EndTime2], ActivitySheet[UserID], ActivitySheet[TransactionType], ActivitySheet[BranchID], ActivitySheet[ActivitySheetDate]),
        FILTER(VALUES(TimeTable[Time]),
            TimeTable[Time] >= ActivitySheet[StartTime2] && TimeTable[Time] <= ActivitySheet[EndTime2])
            )
The virtual table provides all the times between my StartTime2 and EndTime2 Values from my ActivitySheet table using the TimeTable.
I need to create a messure using the virtual table to show when each person worked.
Current:
Expected Output:
[ActivitySheet] - Sample
| ActivitySheetDate | UserID | StartTime2 | EndTime2 | TransactionType | 
| 4/26/2021 | IGARCIA | 7:53:00 AM | 8:41:00 AM | ORD.PICK | 
| 4/26/2021 | IGARCIA | 8:41:00 AM | 8:41:00 AM | OTHER | 
| 4/26/2021 | IGARCIA | 8:41:00 AM | 8:42:00 AM | OTHER | 
| 4/26/2021 | IGARCIA | 8:42:00 AM | 10:50:00 AM | ORD.PICK | 
| 4/26/2021 | IGARCIA | 10:50:00 AM | 1:18:00 PM | WHSE.PICK | 
| 4/26/2021 | IGARCIA | 1:18:00 PM | 2:58:00 PM | ORD.PICK | 
| 4/26/2021 | IGARCIA | 2:58:00 PM | 3:01:00 PM | ORD.PICK | 
[TimeTable] - Sample
TimeTable is in a relationship with [ActivitySheet] on 'TimeTable'[Time] One to 'ActivitySheet'[Startime2]' Many

Hi @EnrichedUser ,

I think you always post the same thing and maybe it sometimes helps people, but your response doesnt relate to anything in this request and is too generic to be useful.
and yes ive read that before.
I was able to get it working using the below messure and making the table a calculated table instead of a virtual one
Working Segment = 
IF(COUNT('Test 2'[Time])>0,
1,
BLANK()
)
It nearly doubled the size of my file and is not a great long term solution.
