Custom fields are not appeared in Related list

Hi, 
I have Opportunity object and I want to show "Thank_You_Letter_Sent_Date" custom field in Related list. However, I can't find that custom field in Related List Properties. Can anyone suggest me how I can display this field in related list?

Hi shelly,

This is not possible as you are trying to display Opportunity custom field as a related list. However, if you want that field to be displayed in activity history related list it is possible by making your custom field "Thank_You_Letter_Sent_Date" for Activity History object instead of making for Opportunity object.

I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.
Thanks and Regards,

Hi Shelly Nyein,

Deepali is right. So if you want to do this thing then you have to do some these steps. 

Step 1. Please Create a field on the "Activity Custom Fields" object (Find from the Quick Find Box).

Step 2. After that you will have to create a trigger for populate the Opportunity field value to the "Activity" field which have created by you.

GIve me a Like if you understand.
