I have an requirement.
Please help me out.
Consider the following sample data,
|Roll number ||Maths||Science||English||Hindi||Marathi|
I want to check if a particular column is missing from the input file.
If it is missing then it should give an error message on the (ANALYTIC APP) interface app that "a particular column name is missing".
if maths is missing then "Maths column is missing in input file" and so on it will check for each column and if all the columns are available then it should execute the analytics app.
I have searched for error message tool under interface category but it is only working with interface tools.
So any solution of how i can get the error message based on condition in an pop window in analytic app.
