Hi,
could you please help me on below scenario.

  1. data table having multiple columns, from this we need to get 3 rows with distinct "date"values from input data.

Ex:Input data

Category Brand Model date
abc1 exe0001 rgg345 9/6/2024
abc2 exe0002 rgg346 9/6/2024
abc3 exe0003 rgg347 9/7/2024
abc4 exe0004 rgg348 9/8/2024
abc5 exe0005 rgg349 9/7/2024
abc6 exe0006 rgg350 9/10/2024
abc7 exe0007 rgg351 9/11/2024
abc8 exe0008 rgg352 9/10/2024
abc9 exe0009 rgg353 9/10/2024

Output:(we can pick any 3 random rows with date as unique )

Category Brand Model date
abc1 exe0001 rgg345 9/6/2024
abc3 exe0003 rgg347 9/7/2024

HI @Manaswini_UI

Take assign activity and use below expression to get distinct value from your datatable
dt.AsEnumerable() _
.GroupBy(Function(row) row.Field(Of DateTime)(“date”)) _
.Select(Function(group) group.First()) _
.Take(3) _
.CopyToDataTable()

Please find attached workflow
distinctrows.zip (48.0 KB)

The image shows an Excel spreadsheet with data on the "Output" tab, listing categories, brands, models, and dates in columns A through D. (Captioned by AI)

Hi @Manaswini_UI,
you can use below Linq expression to get unique and first 3 values,
Take assign activity and enter below expression in value field
builddt.AsEnumerable().GroupBy(Function(x) DateTime.Parse(x(“date”).ToString())).Select(Function(g) g.First()).Take(3).CopyToDataTable()

in To section enter filterdattable variable

refer below screenshot

The image shows a UiPath workflow containing an "Assign" activity that groups a DataTable by date, selects the first entry from each group, and copies the first three groups back into a new DataTable before proceeding to a "Message Box" activity. (Captioned by AI)
