Step by step Issue description :

#1)In our section we have a button to download a template in xlsx format .

#2)The same downloaded file ,Users modify and upload the file for processing .

#3)While processing for getting the data on clipboard we are using MSOParseExcelFile OOTB activity .

#4)When a file of 100 records are uploaded it is parsing the file and giving 100 results on the pagelist.

#5)Issue : When the same file(downloaded file) I modify few values are remove say 20 records from the template also , actually it should parse 80 results instead it is giving 100 results with the old data only.

What we have checked :

#1) We have checked the filepath and it is set with pxRequestor.pyFileUpload

whenever we try to change the name and upload it is updating properly.

#2)At the end of activity page-remove used to remove the list page .
