Following is the screenshot of my client's opportunity object. I find that activity button does not contain Log a Call and Add Task.
Going forward, Log a Call and Add Task are important functions and we need this to be implemented, along with standard pick list for Subject field.
1) I have examined Activity Standard Object for Log-a-call and Add Task standard fields and also looked into Page layout - did not find any solution for adding log a call and add task
2) I have examined activity (related list) under opportunity and i did not find any solution of add them
3) I have examined global Actions "Log-a-Call" but did not find a way as to how to configure it for Opportunity layout
Any help is appreciated
