[Grammar] the function of word

[simon1357]

Hi, I don't know the function of the word highlighted by red color below:

The eventual sales took place timeframe that meant no tax was payable

can anyone help ?

That's not a meaningful sentence. Something has been left out. Nothing can "take place timeframe".
"Timeframe" means what the dictionaries say it does.
Also, it's "time frame".
