Issue/Introduction

CostPlan population errors in both Classic and MUX if a required field exists on the Cost Plan Detail object and the attribute does not have a default value set

STEPS TO REPRODUCE:
1. Go to Administration > Studio > Objects > Cost Plan detail object
2. Create a string type attribute called Cost Center
3. Make the attribute required and do not give a default value
4. In Classic UI, Create a project, Add a team member, Create a Task and an Assignment
5. Go to the Financial Plans and create a Cost Plan
6. Go to the Cost plan details tab > Actions
   Run: Populate from Investment Team
   Run: Populate from Task Assignments
Actual results: You get an Error 500 - Internal Server Error
7. Perform the same actions in the Modern UX > Go to the Project Financials tab and click on:
   Populate from Allocations
   Populate from Assignments
Actual results: Error while Populating Cost Plan from Allocations / Error while Populating Cost Plan from Assignments

Cause

This is due to having a required field that does not have a default value

Resolution

To avoid the error, if an attribute is marked as required, set a default value on it.
