# Exercise: Entity & Entity triggers

## Requirements

Define two triggers for the entity “UserName\_Acc\_customers” (click here to see entity creation steps): 

* After Create Trigger: This trigger is initiated when a record is created in the entity. If the value in the entity field Join\_Date is present, Actions will be initiated to update the value of the field DayMonthJoinDate in coherence with the values of day and month in the Join\_Date value.
* After Update Trigger: This trigger is initiated when a record is updated in the entity. If the value in the Join\_Date or DayMonthJoinDate has been modified after the update, Actions will be initiated to update the DayMonthJoinDate value to be the same as the Join\_Date value.

## Solution

The solution is implemented in two steps: 

* Step 1: Define the “After Create” Trigger to update the value in DayMonthJoinDate according to Join\_Date when a record is created. 
* Step 2: Define the “After Update” Trigger to update the value in DayMonthJoinDate according to the updated value in Join\_Date.
