If it's protected, you simply can't. You'd have to unprotect it first. Or
write a VBA procedure to unprotect, do the fill series, reprotect.

Dear Sir/Mam,
I have a workbook with multiple worksheets. I protected a sheet but some
menu does not work when it is protectd. e.g. i want to go edit fill
series.

How it can be possible.

Thanks in advance
