How to make sure that user can only select himself in the column person datatype?

[qaziosama555]

Hi,

we are trying to automate employee offboarding process for our company. Now the process start when a user inserts a item in list. This is detail about person who is resigning. it contains a person column where he selects himself to initiate the process. the problem is anyone could select anyone and initiate the resign process for the other person. i want the user inserting data to only see himself in person column so that he cannot initiate request for other people.

Thanks
