Hello @Goutham Kannekanti ,
Thanks for the ask and using the Microsoft Q&A platform .
Just to clearfy first the template which you are following is passing a set of parameters to the pipeline , see the snapshot from the same article .
Since we are triggering the pipeline from a TWT we are passing the start and end time as the start time of the TWT and passing that to the pipeline .
In your case the things will change , since you mentioned that the file always arrives once in month , you can pass the start and end time as default as shown below or you can pass the same parameters when you call the pipeline from logic apps ( may the function names will be different , I am not very sure about that )
Thanks
Himanshu
