DHIS2 Import Data issue

Good Morning every one!
I am new to DHIS2 and practicing on DHIS2. I am trying to import CSV file of Data but I think i have deleted some Core values inside dhis2 DB that is why i am not permitted to import Data file.
Following is my structure of CSV.
“dataelement”,“period”,“orgunit”,“categoryoptioncombo”,“value”
“zHUMko8kT5N”,“201706”,“NIB_A_218049”,“JfJhY67ta50”,“198”
