Hi @Kishore_Raj

Check out this thread

In Additional to above find a compacted variation:

Assign Activity:
SegmentSize | Int32 = 50

Assign Activity:
NoOfSegments | Int32 = Convert.ToInt32(Math.Ceiling(dtData.Rows.Count / SegmentSize))

Assign Activity:
TableList | List(Of DataTable) =

Enumerable.Range(0,NoOfSegments).Select(Function (x) dtData.AsEnumerable.Skip(x*SegmentSize).Take(SegmentSize).CopyToDataTable).ToList()
For each Activity: item in TableList | TypeArgument: DataTable

Log Message: item.Rows.Count.ToString()

Hope it helps!!

This should not happen in one go

in the input excel i have 100 records from this i need to run and generate output report with 10 records each time
in the first run it should complete 10 records out of 100 records and generate output file and stop and
in the second run it should complete 10 records from 11 to 20 and generate file and stop and so on it should run in schedules

Hi,

If you can write information for status to the xlsx, the following may help you.
(When process some row, write status Done in the row. In next run, if status is “Done”, it will be skipped.)

Hi @Kishore_Raj

startIndex = 0
batchSize = 10
While startIndex < inputDataTable.Rows.Count
  outputDataTable=inputDataTable.AsEnumerable().Skip(startIndex).Take(batchSize).CopyToDataTable()
  Writerange
  startIndex = startIndex + batchSize
End While
