Data Management Period Override

Content

Hi 

Im using file based upload for data management. and im sending data for several periods using the same data file. I have done data mapping for period and year as well, and it is included in the file too. (PFA)

And i noted something unusual. 

For example: if i have data for oct-20, nov-20 and dec-20, and i executed the data rule mistakenly to a wrong period such as sep-20,

all the data in the file gets exported to the sep-20(incorrect period) overriding whatever is on the data file.

Is there any way, i can ensure system takes the period and year on the file and not on the rule
