This function clears all fields, filters and resets the key to the primary key?

Hi, am new to MS Dynamics NAV.

My question is, which function clears all fields, filters and resets the key to the primary key?

Hi i have gone through CLEARALL function. In that they have mentioned CLEARALL function clears filters, keys and fields of an associated objects. Associated objects means, for example: in form object we are calling some other object such as codeunit? or some other object such as codeunit calling form object?

and also, if we call CLEARALL function, why it clears associated objects keys, filter and variables?
