Hi Community,

Can anyone help me in one thing that what is common between HR profile record and user table record.

The reason I am asking is that I have to update "Title" field in user table whenever "Position" field is being update in HR profile record. 

I had created BR on HR profile table which will run when Position field changes and taken the value of Position field ,now what next?

How should I proceed to update the "Title" field in user table because I am unable to find anything common between these two records from user table and HR profile table.

Please guide, Thanks in advance.
