I have configured a service file, which will eventually be called via a File Listener.
The Service File is parsing records via a Parse Delimiter Rule. And in the parse delimiter build value list option is chosen.

Service File Options. Record at a time, record terminator -\r\n

In clipboard am building the page structure via the parse segment activity as-MyServicePage.TestPagelist(LAST).SampleValueList(APPEND)

Sample file record.
A|B|C
D|E|F
G|H|I

Parsing and Page Structure happens correctly when via Run Option i use 'Supply File Content'
but if i'm using Upload a local file, where the same file content(given above) is uploaded,
cant see any results in clipboard. MyServicePage is blank.

Any heads up is appreciated. Kindly help.
