Hello @Prasenjit Patnaik,, Did you try other trigger types such as Logic Apps? or any other triggers which give full flexibility on custom scheduling window?
I too see that there is no direct out of the box solution for such scenario, but we have many workarounds for this scenario!
One of the workarounds might be:
You can schedule an Azure Data Factory pipeline to run on the 10th business day of the month using a combination of the Schedule
trigger and an Azure Function
that calculates the date of the 10th business day! Your Pipeline's Copy Activity can be controlled in this way!!!
