Solution required for finding 'data gap' in table and adding a new row showing the correct status
- 1 year ago
Thanks for Posting in Microsoft forum Community.
As per the Query you mentioned for Solution required for finding 'data gap' in table and adding a new row showing the correct status. The provided DAX query is designed to find gaps in a table's data where the StartTime of a new row does not immediately follow the EndTime of the previous row for the same PC Name. It then creates new rows to fill those gaps, assigning them the status "Ideal". Here's a breakdown of how the code works:
Step1: First it Creates a new intermediate table (GapRows) that includes additional calculated columns:
VAR GapRows =ADDCOLUMNS(
'Data', // Table name is 'Data'
"NextStartTime",
CALCULATE(
MIN('Data'[StartTime]), // Get the next StartTime for the same PC Name
FILTER(
'Data', // Filtering to get the next row
'Data'[PC Name] = EARLIER('Data'[PC Name]) &&
'Data'[StartTime] > EARLIER('Data'[StartTime]) // Ensure we only look ahead
)
),
"CurrentEndTime", 'Data'[EndTime] // Rename existing EndTime to avoid conflict
)
Step2: Identifies rows where there is a gap between the CurrentEndTime of a row and the NextStartTime of the next row for the same PC Name:VAR IdealRows =
SELECTCOLUMNS(
FILTER(
GapRows,
NOT ISBLANK([NextStartTime]) && [CurrentEndTime] < [NextStartTime] // Detect gaps
),
"PC Name", [PC Name],
"Status", "Ideal", // Add status as "Ideal" for the gap rows
"StartTime", [CurrentEndTime], // Start time of the "Ideal" row is the current EndTime
"EndTime", [NextStartTime] // End time of the "Ideal" row is the next StartTime
)
Step3: Combine Original and Gap Rows:RETURN
UNION(
'Data', // Combine original data
IdealRows // Combine with the newly generated Ideal rows
)
Using the above code, I obtained the expected output. I opted to use "Ideal" instead of "Unavailable" to enhance clarity and understanding.
By utilizing conditional formatting, I was able to highlight the desired results.
Using the Background Color feature, I set a rule to get the desired results.

Hi danextian
Sorry my late response, I have not had much time working on this.It worked fine with the sample data, but it's not working on our production data.
Something is going wrong with the 'previous end time' calculation..
I hope to get some time in the new year to look into it.
Thank you for your help 🙂
